...done. Improvements welcome.
Should there be some specific place where admins can report ISP proxies so that a developer can check them, with a list of proxies that have already been checked and found wanting? An admin doing vandal blocking generally can't tell if a proxy provides XFF headers or not, but I understand that the headers are logged in the database where developers (and those with CheckUser privs?) can access them.
