Hallo, Platonides,
Du (Platonides) meintest am 30.09.08:
I see you've been putting all the offending IPs into the blocked IP list. That has limited value since the IPs of spammers change so often.
I use the CIDR notation - that's enough for x.y.z.w/16 nets.
Interesting approach: "As captcha blocks the good guys, it's better to block the subnet"
Blocking the subnet is not my first counter measure ... Some nets are abused by many bad guys, and the abuse department doesn't block them: then I block that net.

Viele Gruesse! Helmut
