My blog has been getting hit hard by spammers (you probably noticed if you subscribe to Blog@Case Comments). I use the MT-Blacklist plugin to mark every one of them as spam, so I figured I was doing some good... but it keeps letting them through, even if the URL patterns are obviously similar.

So I checked the MT-Blacklist page and noticed that it says only 39 URL patterns are blacklisted. Huh? Does it just add all those as string patterns instead? If so, even that's not working; I still get spams with the URL dunetribune.info even after de-spamming all of them.

Is our spam filter working? Am I just not seeing the tidal wave of messages that are actually coming in? Why don't I ever see any spam on Mano Singham's journal (and I'm subscribed to Blog@Case Comments, so I'd see them even if he deleted them afterward)?
