First off, I realize this is an old thread, but its content is still very much relevant, so I don't feel too bad about 'bumping' it. I agree that being able to cross reference banlists across various SSC zones is a good method of maximizing efficiency in keeping undesirables banned. However, while the current system (designed by Rudy) is great, it does have a major shortcoming - it isn't "real-time". It might be possible to improve on the current system by having a system of "reciprocal BanG access" in participating zones, where the main BanG op (and only the main BanG op) at each zone has L3 access at the other zone for purposes of being able to view bandata in "real-time". (Why L3? L4 can't view IP addresses.) I'm reasonably sure the main BanG ops at most SSC zones can be trusted not to use L3 access at another zone to ban people, or otherwise abuse this access by using it for anything other than the purpose of getting bandata. Besides, the system would only be set up between zones where both zones are willing, so no zone would be 'forced' to grant access to an op they might not trust. Thoughts? Or is this proposal completely ludicrous for some reason I may not have thought of?
