Admin Forum:Is there a way to block proxy providers or edits made from proxy IPs?

As the topic title states. I am asking this because there is a user that has gone out of their way to be an annoyance using Talk Talk three times now and dealing with them is getting old. Message 12:54, June 11, 2012 (UTC)
 * Unfortunately, blocking open proxies would block a lot of legitimate users, and we'd never be able to get them all (IPs change all the time) - we might be able to block an abusive range of IP addresses, can you give us a list of what IPs/users have been a problem? --  Random Time  14:37, June 11, 2012 (UTC)
