Quote - I fear this will not work for some very simple reasons.

An offender starting a fight, wants to fight @ win, and will continue posting in public.

A troll that starts to troll ; That is his/her sole purpose!!!! 

Trolling in private does not bring the same "satisfaction", they need the audience and they drive on the attention.

It may, or it may not. Won't hurt to try. Ultimately, the real threat here is the moderators, and bringing them into it. But the POINT is to keep the threads from being locked. Some one comes trolling, we notify a mod and let them deal with him. Yeah, the trolls may be hard to control, but once again, if no one feeds the trolls they'll go away.
