Blogspammers are persistent little boogers

Just an observation while I wait for my lunch – I’m getting several obviously-fake user registrations a day here now.  It makes no difference, since registering as a user doesn’t immediately allow mass un-moderated posting, but seeing the stream of notices from the blog IS slightly annoying.

Also, blogspot sucks.  Apparently a few years ago some dork made a “blogspot” theme that hotlinked (idiotically) a blank white graphic on my other webserver.  Why they didn’t just use a background colo I have no idea, but now there is a mass of blogspot blogs in Indonesia, Pakistan, Azerbaijan, etc now clogging my webserver’s log with requests for this now-non-existent file.

I need to find a massive site-choking graphic I can redirect them to until they knock it off.  Any suggestions?
