Topic on All The Tropes talk:How We Do Bans Around Here

Just added a reason for an immediate tempban that we've had in place for years now. As for when we shift from temp to perm, well, we had someone on a 4 month tempban which expired in November. IIRC, we promised a permban after that, so we a have a precedent to follow: if we reach a point where we're going tempban someone for over 4 months, we might as well permban.

One thing maybe we should also have is a schedule of tempbans -- do different offenses merit different initial ban lengths? And should we have a predefined series of durations -- one day, 2 days, 3 days, 1 week and so on?
