If You Comment On Blogs Extensively, You Should Consider Using Google 2-Step Verification

One recently identified cause of deleted Blogger blogs appears to involve brute force hacking against our Blogger / Google accounts.

We've known, for some time, about blog owners receiving alerts about "suspicious" / "unusual" account activity. The alerts frequently involve locked or deleted Blogger / Google accounts - and generally include the owner having to change their password, solve a CAPTCHA, and / or provide their phone number (mobile or home phone) to login.

Later, people started reporting that their blogs were being deleted - possibly as a result of having to change their password, solve a CAPTCHA, and / or provide their phone number.

I've been observing - and blocking - an annoying style of comment based spam, which I have termed "nice blog" spam, for some time.

Nice blog. I will keep visiting this blog very often.

This style of spam, from what I can tell, has been published by the millions, in various blog comments, on both Blogger and non Blogger platforms.

The reason for the spam always intrigued me. Observing that the spam was published in the millions, suggested to me that it had a special purpose, intended by its creators. Looking at a typical spam message, in my email (since I moderate before publishing), I could see no consistent type of content.

• Some messages would contain links, others not.
• Some messages would mention what looked like commercial products, other references were obviously imaginary targets.
• Some messages would appear to be mere babble.

Recently, I discovered one strong possibility for the purpose of the spam - a very ingenious form of email address mining. The spam comment is only needed to allow a hacker to subscribe to a given comment stream, using the "Email follow-up comments to ..." option. It's possible that the subscription is not even affected by moderation - whether the blog owner is moderating, either before or after the comment is published to the blog, the hacker remains subscribed to the comment stream.

All that the hacker / spammer has to do is to publish a spam comment, select the "Email follow-up comments to ..." option, and watch while his Inbox fills up with subsequent comments from other Blogger / Google / OpenID account owners. Any comment containing an email address, and linking to a Blogger blog, would go straight into the hackers database.

Later, the hacker could go to work against the Blogger accounts referenced in the comments. In some cases, this would result in successfully hijacked Blogger blogs, which would become part of a spammers blog farm where advertisements of various nature could be hosted. Valuable blogs, with established reader populations, could also be used to serve malware (and more hacking) to unsuspecting readers.

The demographics of some hijacking attacks provide interesting clues. In one episode, we had a significant number of home / personal / small business blogs that had been hijacked by one specific individual. Many of the victim blogs

• Contained details relevant to the owners, which provided clues to passwords used by the owners.
• Were owned by people who used commenting extensively, for networking both with friends, and with business targets.
• Were read (and commented upon) by similar people, who similarly provided password clues in their own blogs.

Having been part of the restore process, both with people who had their blogs hijacked, and who had their accounts locked and blogs deleted, I observed that the former (hijacked blogs) seem to have decreased in volume as the latter (accounts and blogs locked / deleted) increased in volume. I don't think that the relationship is coincidental - or spurious.

My opinion is that the locking of Blogger / Google accounts - and subsequent deletion of blogs - directly results from detected attacks against the accounts in question ("suspicious" / "unusual" activity). Noting that the attacks seem to be more common to people who comment on blogs as a form of networking, it appears that commenting can lead to accounts and blogs being locked or deleted, as Google protects us against hacking.

Considering this possible cause and effect relationship, Google 2-step verification is a good idea. Click here, for Google instructions on setting up 2-step verification.

Use of 2-step verification helps safeguard our accounts against brute force hacking. This will help anybody who is anxious about accounts and blogs being deleted or locked, as a result of "suspicious" / "unusual" activity. If you own a blog which is subject to this threat, you should consider using 2-step verification.

The sanity (heart attack, ulcer) that is saved may be your own.

Control The Email Settings, Relevant To Your Blog

Some blog owners don't always think about the various email settings, which are part of their Blogger blogs, and the possible effects to their email - or somebody else's email.

There are several settings, where a blog owner may enter an email address.

• Email posts to
• Comment Moderation.
• Comment Notification Email.

These settings don't require acceptance by the recipient, making for some interesting possibilities for causing problems in other people's email, as well as one's own email.

There are several Blogger dashboard settings - related to post publication and to various commenting activities - with differing effect to one's own, or somebody else's, email.

• Settings - "Mobile and email" - "Email posts to" - aka "BlogSend" - generates a minimally formatted text copy of each post, when published, to up to 10 email addresses.
• Settings - "Posts and comments" - "Comment Moderation" generates a minimally formatted copy of each incoming comment, before the comment is published - and allows moderation of the comment, while reading the email message - when the recipient has the proper authority.
• Settings - "Mobile and email" - "Comment Notification Email" generates a minimally formatted copy of each incoming comment, before the comment is published or rejected.

Since none of these settings require acceptance by the recipient, there are various possibilities for causing interesting email delivery.

Unlike various subscription services which use email, such as a FeedBurner Email Subscription service, an email address added to any of these three settings requires no formal acceptance. If a blog administrator should add an email address, whether their own (primary or additional personal email address), a willing friend or relative, or an unknown victim's address, there is no initial email sent to the recipient

You (or somebody else) has added this email address as a recipient of "Email posts to" / "Comment Moderation" / "Comment Notification Email". Do you approve of this additional traffic source to your email service?

or a similarly worded notification / approval. Given a clueless or malicious blog owner, it's possible that one (or all) of these settings could be used to harass an unwitting third party, or to (unwittingly) confuse oneself.

The "Email posts to" feature, also known as "BlogSend", generates a minimally formatted text copy of each post, when published, to up to 10 email addresses. This setting has been used, in the past, to provide distribution of newly published posts for private blogs, as well as a simple distribution for posts from public blogs.

Since it's limited to 10 entries, BlogSend does not provide a suitable service for any blog with a reader population of any appreciable size. For a blog owner with any technical experience, FeedBurner Email Distribution is a much better solution for post distribution - when the blog in question is publicly accessible.

For distribution of a private blog to more than 10 readers, one may use Google+.

The "Comment Moderation" and "Comment Notification Email" settings, used together, can generate interesting duplication of email to one's own (or somebody else's) email service. If these settings are made without thinking, some interesting confusion can result. Email addresses can be added to each of these settings without consideration of the relationship or level of authority enjoyed by the owner of the email address, relative to the blog in question.

Comment Moderation Email is presumed to generally be a function performed by blog administrators - but email resulting from this setting will be sent to anybody addressed. A blog administrator / member - or other non administrator of the blog or an unwitting stranger - will receive email suggesting several options,

Publish
Delete
Mark as spam
Moderate comments for this blog.

If the recipient is not an actual blog administrator, the links in the email provide confusion, and no result.

Comment Notification Email might be generally addressed to blog members - but is not necessarily limited. Since notification of comments is sent separately from moderation, recipients of a notification can become confused when they fail to find the comment, mentioned in the notification, present on the blog.

A blog administrator, using either an email moderation message - or using the blog Comments wizard, may or may not decide to Publish - or to designate a comment as Spam - regardless of a notification message having been delivered to each designated recipient.

Comment notification email may look similar to comment moderation email, less the comment processing options - possibly causing more confusion. A blog owner, adding his own email address to both comment moderation and comment notification, may see the combination as unknown duplication. And blog owners may confuse the proper use of comment moderation and comment notification email.

A blog owner, transferring ownership of a given blog, may overlook updating of the email settings. A new blog owner, receiving a blog being transferred, may likewise overlook these settings, and may lack the associated email, until the omission is corrected.

Either the previous owner, or the new owner, may be confused temporarily - and may wonder why they are still getting email / not getting email, until they examine and correct the setting in question. Alternately, if someone's email address was added maliciously, by a blog owner intending to harass somebody, one can see interesting possibility for conflict.

Everybody Won't Get Proper Notice About Their Blog

One problem that we're seeing in Blogger Help Forum: Something Is Broken involves blog owners, who recently discovered their blogs deleted or locked, by Blogger - and without any notice received.

The account actions may be required with the blog deleted for a suspected TOS Violation, such as hosting malware, porn, or spam - or locked because of "suspicious activity" on the Blogger account.

Why was my blog deleted? I never got proper notice!

Too many people depend upon email notification - and may not receive proper notification, in all cases.

Blogger provides a dashboard based malware / porn / spam classification notification / recovery process, which may not be available for everybody. Similar to malware / porn / spam classification, there will be issues with DMCA violation notification.

This is also a problem when accounts are locked for "suspicious activity", and when blogs are locked for hosting malicious third party gadgets.

There are several reasons why some blog owners won't get notification of their blogs being deleted or locked, by the various Blogger / Google security processes.

Nobody should expect advance warning of any action being taken.

Besides notification limitations, nobody should expect to get advance warning of action being taken - as this would simply encourage the intentional spammers to never request review. Intentional spammers, if permitted, would play 3 Card Monte, endlessly, with their spammy blogs.

Both the notification, and advance warning, limitations contribute to confusion about the various Blogger / Google security recovery options. All email based notifications may not be properly delivered.

The owner of any email account, which may not deliver email properly, is still responsible for reading any important email messages.

Some blogs are owned by accounts which use intentionally bogus email addresses.

Too many Blogger blogs are owned by Blogger accounts which are based on inactive or nonexistent email addresses. Owners of these blogs will never see email notification, when they - intentionally or not - make themselves anonymous.

Some email clients may misfile an incoming email message.

In other cases, some people may get the email notifying them of problems - but their email program may misfile the email, in a folder which they may not check, regularly. In some odd cases, somebody other than the owner may get the email.

Blogs owned by teams will be subject to action against any one member.

In team blog ownerships, any blog owned by the team is subject to action, against the Blogger / Google account, used by any team member. Blogs affected will simply disappear from the dashboards of all team members - with no opportunity provided for appeal or review.

Some blog owners maintain too many Blogger and email accounts.

Finally, too many blog owners maintain multiple Blogger / Google accounts, and are not completely sure which Blogger account may own a given blog. These owners may not even see the dashboard based "Deleted Blogs" button / link, because they will be logged in to the wrong Blogger account.

Each blog owner is responsible for any problems, regardless of cause.

Not all of the above scenarios are entirely the fault of the blog owners - but the blog owners are the ones who will have to deal with the resulting problems. It's possible that this may seem unfair - but it's reality.

Use Of Google+ For Networking, And Keeping Your Blogger Account And Blogs Safe

One constant activity in Blogger Help Forum: Something Is Broken involves blog owners whose blogs were deleted - either righteously or spuriously - as part of the ongoing battle against spam, in Blogger blogs. Generally, the problem comes directly from the blog content.

Sometimes, the problem is more subtle.

When I tried to login to Blogger, I got a screen that said my account needed to be verified, due to "unusual activity on my account". Having verified my account, I see that my blogs have been deleted.

This is part of one of the more intriguing episodes, in the never ending fight against hacking and spam, in Blogger.

Some Blogger blog owners participate in comment based discussions, and provide their email addresses there. Some state their email addresses openly, in the body of the comments, for the world to see when viewing the comments. Others post comments using their Blogger accounts, knowing that the blog owners can see their email address in the comment moderation / notification email messages - and can contact them using email.

Spammers use comment based networking, to their advantage. They subscribe to any comment thread, using the "Notify me" option - then wait while blog readers comment using their Blogger accounts. As the email comes in, from blog readers commenting, they scrape the email addresses from the email content. Since most people commenting either openly state their blog URLs in the comment bodies - or link to a list of their blogs - the spammer now has two essential ingredients, to be used for hacking someone's Blogger account, and gaining control of the blogs owned by the account.

Google now provides Google+, where we can network with a designated audience, and avoid spam in our email. Using Google+, our email addresses are not revealed, and spammers have less incentive to use Google+ for email address harvesting. This protects our Blogger accounts and blogs against hacking, and relieves us from email based spam.

For people who update their Blogger accounts to use Google+ based profiles, but continue to network using Blogger comments, Blogger now protects us by using anonymous email addresses in all comment generated email. This leaves people who continue to comment, using Blogger accounts with native Blogger profiles, vulnerable to ongoing email address harvesting, and account hacking.

Blogger account hacking, using email addresses harvested from Blogger blog comments, will typically involve brute force password guessing. Blogger, detecting brute force attempts against a vulnerable Blogger account, will lock the account and the blogs. Once we verify ownership of our Blogger account - and hopefully change the Blogger account password to something less vulnerable to guessing - the blogs owned by a possibly compromised account remain locked, until they can be examined for signs of tampering, by Google security / spam analysts.

We also must consider the possibility that not all brute force password guessing attacks are being detected by Google - and some Blogger accounts are being deviously, and temporarily, hijacked.

People who setup Blogger accounts based on bogus email addresses - or who have accounts based on old email addresses which they can't use - continue to present a challenge here. These people will never receive essential email advising them of a problem in either verifying their Blogger account - or their blogs. This will continue to make our initial spam lock advice relevant.

Can you login to Blogger? Do you have a dashboard link "Deleted blogs"? That's where you start.

You wait 24 to 48 hours after submitting a Restore request - then you post back here, and we take the next step.

Blogger Comments Being Posted Using Anonymity

Some Blogger blog owners use their Blogger blogs as the center of their peer to peer networking life.

Many blog readers are expected to post comments - and to leave their email addresses, as part of their message or profile, to allow direct contact. Long ago, I used the email address of my commenters, as part of an easy "Contact Me" form, on this blog.

Recently, we've been noting that Blogger comments don't always include a useful email addresses - many comments simply describe the commenter as

noreply-comment@blogger.com

Not all blog owners - and readers - appreciate this change.

When I leave a comment using my google profile, it isn't linking my profile with my email address. How do I get my email address properly displayed?

and

Why do so many comments, published to my blog, show the email address of "noreply-comment@blogger.com"? How do I email my readers?

For some time, we've known of the dangers of revealing your email address to the world, in general.

Blogger blog owners have been a known special risk, with their email addresses. Google developed Google+, with the Google+ profile, to allow everybody to network with their friends - both old and new - without the risk of revealing one's email address.

Google+ replaces email completely. You can share comments, messages, photos, and videos with anybody, in a self contained universe - and you can define your own, personal universes. This leaves the need to reveal your email address completely unnecessary (though you can use email, if you wish, without knowing anyone's address - or revealing yours).

After Google+ became popular, Blogger added the option to link our Blogger blogs with our Google+ profiles. Blogger profiles, based on Google+, are cleaner, and use the Google+ displays to update.

To encourage people to use Google+ for peer to peer networking activity, and to make our Blogger accounts and blogs safer, Blogger has eliminated our email addresses from all outside correspondence - including when we publish comments on Blogger (and non Blogger) blogs, using a Google+ based Blogger profile.

If we publish a comment on somebody's blog, and the blog owner has enabled comment moderation or notification, our comment shows up in the email inbox of the blog owner - but with our email address displayed as "noreply-comment@blogger.com".

With email addresses not displayed, this helps protect our Blogger account names from becoming unnecessarily revealed. Blog owner - reader comment communication is still possible - but again, without the email address of the reader being known.

By eliminating our email addresses from our comments, Google is helping to protect our accounts and blogs, while letting us continue to comment on each others blogs - and to eliminate one type of unnecessary spam from our blogs.

Google+, which replaces email for networking, uses a "Friend of a Friend" relationship to let you expand your universe infinitely, with each comment, message, photo, and video that you share. It lets you control the expansion of your universe - if you wish. And, it helps keeps your Blogger blog under your control.
