Movable Type

As you can see, the spam robots are killing this blog. I previously used JayAllen’s excellent MT-Blacklist plug-in, but now I’ve upgraded to Movable Type 3.15. MT-Blacklist is not supported on Windows servers running MT 3.15. So what are my options (aside from making everyone register to comment.) I want to block certain words like cheap-pills and onlinepoker, like I used to do w/ MTBlacklist. Help please!
