My blog has been getting tons of comment spam lately. I moderate comments, so they never appear online (though there's a bug where not-visible comments still increase the counter on the main page), but still...every morning I get to log into the moderation page and click "delete all." Some of the stuff is filthy...like the one with links to twenty different types of rape porn--no, seriously. Mostly it's for viagra, etc. There was a funny one today that started with "sorry for this post." These guys seem to know what they're doing, since the IPs seem to be random. I also employ the rel="nofollow" trick, so even if they made it online (which they won't), they wouldn't have the desired effect of increasing their page rank. Anyway, thought I'd share.
