Yeah; I'm just going to assume that most if not all subs are SRS controlled. There needs to be a usermap axe feature; so that you could ban all of someone's alts if they've ever been accessed by the same IP address. To better combat the SRS threat; and then issue Kill on Sight orders so that any new alts they make are banned after that. That's the only way to get people off the site if they use it in a breaking it way.
