This is my issue. I'm a site administrator at a Christian forum who has had more than my fair share of problems with spammers. I've managed to solve the majority of them but there is one that has been a continual thorn in my side for years now.
My "membership registry" is being spammed by as many as 50 psuedo members on a daily basis and I'm at my wits end over how to put an end to it once and for all. Do any of you technical experts have any suggestions? Any input would be more than well appreciated.
