Craig over at Gearbits continues to get pummeled by comment spam… Craig have you tried MT-Blacklist? unless you upgrade to MT3 and use Typekey or just turn comments off and go with trackbacks and Technorati, this is going to continue… damn spammers!
I’ve been very successful at blocking spam comments in WordPress, btw. It’s not a problem at all there based on some settings in the prefs…There’s even a blacklist plugin, though I have not found that to be necessary just yet.
