How to stop spam bots on vb 4.x?

[thenags]

I've tried the Q&A verification with about 6 different pretty good questions. No answers given away in the question, no simple math problems, etc... spam kept flying in.

I've been testing out Glowhosts Spam-O-Matic all day and it's catching quite a bit of spam but it's also letting in about 2 spambots for every 8 it blocks.

I've now temporarily disabled Spam-O-Matic and I'm testing out KeyCaptcha to see if that can get 'em. Hopefully this works.

I really wish we had the option of enabling 2 Human Verification options. I'd love to have KeyCaptcha on as well as a Q&A.
