Incidentally, my (default) proxy (194.117.133.196 cache-haw.cableinet.co.uk) is banned again - my ISP also caters to the recent goatse.cx vandal. I know how to manually change my proxy, but other valid users on Blueyonder in south west England ([[user: Nosrail]] for example) may not.
Perhaps there's a way we can make use of the 'Client-ip' and 'X-forwarded-for' headers which are added by many ISPs' proxies.
I think it would be necessary to decide whether the actual IP address seemed to be a shared proxy or not when imposing the ban -- simply matching against these headers whenever they were persent would just make it easier for people with fixed IP addresses to avoid the ban.
It wouldn't help people with short-term IP address leases at all, of course.
