A Blam (Blog Spam) Attack – What it Looks Like

Comments (10)

It’s Sunday evening and I’m sitting at my computer catching up on email from the weekend listening to The Pros and Cons of Hitchhiking by Roger Waters. Amy is upstairs watching The Horse Whisperer, which I have no interest in.

I receive an email from with the subject line [Feld Thoughts] New Comment Posted to ‘What do my blog stats really mean?’. I know this is an email to approve a comment. A little warning light goes off in my mind since this is an old post, but I hit Reply and send back an email that says “Thanks for the comment.” I then go to approve the comment and as I’m doing this, notice that the comment info is as follows:

IP Address:
Name: オンラインカジノ
Email Address:

Wonderful work. I enjoyed read your site a lot.


While I’m thinking about and why it would be in the post (duh…), my email thank you bounces: on 6/13/2004 8:13 PM
You do not have permission to send to this recipient. For assistance, contact your system administrator. #5.7.1 smtp;550 5.7.1… Relaying denied

Then – nine more emails show up in my inbox – same drill – but comments for different posts. The emails are from,,, and

A pattern clearly has emerged.

I delete the emails and go to Movable Type and delete the comments. It’s pretty clear where this is going.

    This happens to me nearly every day over at the blog I keep for the Santa Clara County Democratic Party. This is the only blog I have that uses Movable Type. I have other blogs on Blogger and one on iBlog; none of these have the problem.

    They are always from the following email address:, which I have never tried to email to see if it is real, since my email address is not published anywhere at that blog.

    I have not turned on pre-approval of comments, but reading your post, I guess that’s what I’ll do. This spammer posts more fake comments than real commenters do anyway.

    I have noticed other bloggers, such as Wil Wheaton getting slammed in this way too.

    Blogging may become just one more great communication tool that is going to get destroyed by constantly new forms of spam.

    of course these domains are probably impersonated. It really upsets me.
