I had 60 comment and trackback spams overnight. All but one of them were for the same URL. By the time I got through MT-Blacklist removing them, it had already blocked 5 more attempts to spam the same URL.
The problem isn’t keeping up with the URLs that they’re spamming – that’s never going to be completely under control, but MT-Blacklist does an ok job. The problem is the compromised PCs that the spammers are using. Last night’s spam run involved about a dozen different IPs – you can bet your life that ever single one of them is some idiot’s home PC that’s been taken over by a virus, trojan or spyware.
I can’t keep up with that list of IPs, but I bet there is a clearing house out there, and a plug-in for *some* blog software, that will. Any suggestions?
