Re: PHP formmail getting spammed by bots

Well, I'm not getting spam that's duplicate. It's from the same bot but
differant messages. I can mail you some of them if you think it would
help. But anyway, I noticed half of them were not being refered from my
site and the other half were. So I'm now checking if the referer is
blank etc. But now that I've given it more though, I don't think a fix
can be done :(

I don't want to make my users have to go through any verification
clicking/typing but I don't want spam from bots either... Any more
suggestions?
