Yeah, pretty easy hey. Unfortunately it doesn't seem happen that way DBI.
I'm keen on an opt in only area where a 'problem thread' is punted off to if it starts to get unruly. No stifling of the debate by having to remove posts or moderate, rather, the thread is moved to an area where registered members who have 'opted in' can duke out an issue without disturbing disinterested members or guests. If a participant then takes offence about something in that area or gets their nose bloodied, well too bad so sad, they opted in for it.
A couple of forums I subscribe to have such an area for 18+ humour. It seems to work well for them.
