... blog-on-blog action , comment_spam

So my blog-comment-spam problem has gotten somewhat worse... For a
while it was just a few coming in every now and then. A few weeks ago
I got a bunch all in one day, which prompted me to finish the code
that I'd started some time before which allows me to very quickly and
easily delete a comment. When I did that, it turned out I actually
broke posting comments entirely for a little while (which turns out to
do quite a good job of stopping the spam, actually!), but then I fixed
Then all of a sudden today, I got a big wave of them -- it appears
that someone actually went to the trouble of automating the posting of
spam to my site. It's already pretty odd that anyone would have
bothered to do that, since their scripts are not going to work
anywhere else on the web... But wait -- it gets weirder.
When I added the code to delete comments before, I also added code to
allow me to blacklist particular URLs, so if a commenter posts with
one of those URLs, their comment fails to post. So very quickly,
after these spams started coming in, I added their common URL to that
list. Since they all used the same URL, it was of course trivial to
just block them all, so for the rest of the day today they kept
posting to more of the entries on my site, but none of those comments
actually showed up on the site even for a minute.
And here's the weird part. I just discovered that the URL they were
linking to is not even a registered domain.
So ... this wasn't the usual type of "inflate-my-Page-Rank" comment
spam (which of course doesn't
even work anymore anyway, but you know, I was thinking maybe the
comment spammers hadn't figured that fact out yet). It's just
... graffiti. With no purpose at all.
I don't get people.
