I hate spammy spammers, (no offence kregg).

I want to ban them from my site, but, short of employing a mob to shot them all down, I was considering baning IP addresses.

But, a point of which I had picked up on the t'interweb is that because IPs change it will never prevent spammy spammers, and potentially annoy the good people, such as myself...


Any thoughts / alternative suggestions?
