Blogger Does Not Moderate Comments For You

Almost daily, some optimistic blogger asks in BHF: How Do I? the question
How do I report unwanted comments?
as if Blogger has a classification in the Report Abuse form for spam comments. Unfortunately, they do not.

There are 4 levels of authentication, permitted at the option of the blog owner.
  1. Anyone / Anonymous.
  2. Registered Users / OpenID.
  3. Users with Google accounts.
  4. Blog members.
With options #1 and #2, Google has no control at all. If the blog owner chooses to allow comments to be published by anybody, or by anybody externally authenticated, Blogger commenting has no choice but to accept the comment being published.

With option #3, and since a Blogger account has no intrinsic value comparable to a FaceBook or Twitter account, were Blogger to block or delete any Blogger account for attempted spam comment publication, it would be a trivial effort for a spammer to switch to another Blogger account.

The more active and persistent spammers use many different identities, and many different IP addresses (generally through a botnet). Neither Account nor IP Address filters have any real chance of making a difference.

With comment filtering, Blogger takes the only practical strategy, and allows the blog owners to select which comments to allow, in their blogs. As to which comments are to be moderated, and when the moderation is to be conducted, that is the decision of the blog owner. The blog owner can choose to train the spam filters, which will use collaborative heuristics to detect and remove mass submitted commercial comments. Simply unwanted comments, though, are the personal business of each blog owner.

It's that simple.

(Update 2010/07/01): It's possible that Blogger is doing something about the problem of spam comments, by removing the motivation behind spam comments.

My question is maybe not about comments, but about people emailing my blog all there a way to trace that? I recently received an email of my own blog with a ridiculous email address associated. I did an IPTrace and it gave me back google. If it is someone just messing around, I would like to stop them without taking the ability to email my posts. Is there a way???

is there a way to trace that?

Email can be traced, but only to a limit. Email forwarded generally can't be traced before where it was forwarded. Email delivered through a GMail server generally can't be traced before that, either.

The latter details is why many spammers, and some security experts, like GMail. Its use increases your physical anonymity, in a way that many web based email systems do not.

Thank you! So, from what I take from this is the best way to combat this is to take the email capability off of my blog. At least then people would be forced to use their own email account (or one they set up, but it would possibily be more traceable than the email capability directly from the blog itself)??

can I just thank you for this whole blog...I have learned so much from you!!! :)

The email capability, on your blog, uses the email account of the reader. The envelope icon is a shortcut to an email client that uses email setup by the reader.

If you do not want people to easily email information about your blog to their friends, removing the email icon will do that. It won't do a lot about the spam though.

And people who really want to email information about your blog will do so, using their own email client, intentionally.

One person persists in sending nasty messages to my blog and has been doing this for years. I file the messages in a folder saved to my computer. I did not realise there was an email facility. I will look into it. Thanks

Stats Components Are Significant, In Their Own Context

One popular Stats related accessory, which displays pageview information to the public, is the "Popular Posts" gadget.

Popular Posts identifies from 1 to 10 of the most popular posts in the blog, by comparing Stats pageview counts. Optional parts of the display of each post are a snippet of text, and an ever popular thumbnail photo.

Like many Stats features, blog owners have found imaginative uses for "Popular Posts" - and overlook the limitations of the gadget. Both the dynamic nature of Stats, and the timing of the various pageview count recalculations, create confusion, when Popular Posts is examined.

Help! I Can't See My Blog!

I just posted to my blog, so I know that it's there. I can tell others are looking at it. But I can't see it.

Well, the good news is you don't have a blog hijack or other calamity. Your blog is not gone.

Apparently, some ISPs are blocking *, or maybe have network configuration or infrastructure problems. You can access or you can access, but you can't access, or

You can't access them directly, that is. If you can access any free, anonymous proxy servers, though, you may be able to access your blog.
