If the Java Script support that was added has integration to banning people and IP checks and things like that, you could make a banning program to ban all of the accounts at an IP except for one account and it could be used in these scenarios. Also, you could make one that checks the IP of users as they register and adds it to a database organized by IP, and then when one of those accounts is banned you could manually ban all accounts at that IP except for the one you want unbanned.
