MT-Blacklist/Comment Spam Clearinghouse: Introducing SpamLookup
I've been using MT-Blacklist for a while, but now it looks like its time to convert to
SpamLookup, a new plugin by Brad Choate. Even the author of MT-Blacklist thinks folks should switch.
It adds many more rules for preventing spam, which everyone needs. I'm up to 35,000 comment spam alone blocked for the last three months.
