I am quite happy to supply information to a main Administartor who would implement this system but more over I wondered if TW themselves would consider taking part in this venture by providing some means of reporting a banned list via a server update?
Again this would only be a means of reporting a banned player to an outside server where the list could be compiled but would be a huge boon to RO Admins if they wish to move forward with this venture.
I would suggest that perhaps Tripwire might consider creating a forum for contributors to the ban list, for discussion of why someone was banned. If you guys are interested in having me work on the back-end and/or file server support, get me in.
Not to speak for TWI, though, but I wonder if they'd be a bit hesitant to unleash such a server list. That might amount to a tacit endorsement of a third party's judgment without review, e.g., they're helping ban someone from their game -- paid customers -- based on someone else's opinion with which they're not intimately familiar.
If there can be no strong censensus on some of the potential reasons for bans (e.g., some don't think racism is deserving of a permanent ban, and others do), perhaps it might be possible to automate the process to offer several lists, e.g., racism bans but no offensive name bans.
