While I’ve been pretty successful in suppressing comment spam, I still seem to have some trouble with trackback spam. I believe there are some decent WordPress solutions out there now, but I haven’t really had a chance to play with them.
In the mean time, I decided to start filtering out all comments that contain the word Texas, as I’ve been getting a lot of spam for Texas Poker and Texas Hold’em, and for some reason Wordpress (at least my version) seems to be unable to recognize the word hold’em as a spam word… If you’re from Texas or need to comment on Texas for one reason or another, I apologize in advance. :)
