Sorry if any of you got spam comments emailed to you this weekend. Since I put my new anti-spam technique in place, about 15 or so spam comments have gotten through. A majority of them were from the same bot I think, so if I can stop this guy, then I think I would be good.
I have updated the ColdFusion code to tweak the reasons that form submissions will get blocked. I think this final step should be pretty good as it really attacks the reasons why spam bots are so effective - they are so darn fast! If this finally works, then I will write it up on Monday as it is soooo simple.
Fingers crossed again.
