Question about spamfilter

[violet94]

I'm wanted to open a forum on my site years ago but it kept getting spammed, so i shut it down.
I just wanna know, what spamfilter do you use on this website?
It appears to do a good job.
Thanks

Human spam filters I'm afraid.

The question on registration helps filter out some spammers but mostly the board is set to require approval for a user's first posts so you don't see the spam.
