This is the classic troll wedge. Some people will say "they're banned, we want nothing to do with them". Others will say "they're not bothering me, let them stay". There will always be a line.

Actually, you don't even have to go for the slippery slope argument. Rewind back to "Some people will say 'they're banned, we want nothing to do with them'. Others will say 'they're not bothering me, let them stay'." Hey presto, we're wasting time arguing on behalf of a banned troll, instead of doing something productive, and -- the troll has trolled us into doing it.
