guest posting abused
I'm running a message board (a homemade php/mysql board) on one of my sites. I allow guest posting with it, thinking that if some people start spamming I can just ban their IP. Well... Guess what! Some guy is posting a few really ugly messages each day ( with some really bad words I do not want to repeat here ) using a completely different IP (not just ie. 65.65.65.<random> like a dial-up user might but random.random.random.random) address each time he posts ! How the hell do I stop this guy without stopping guest posting (I really want to allow guests to post :/)?
