As entertaining as that may be, it won't solve what you are hoping to solve.
Most thread gets derailed slowly from the OP, to whatever fac. v fac. or 1v1 drama, bullshit, etc. it can be stretched out to.
I.E, pvp video thread as most cases will end up with arguments and insults caused by one side giving random excuse for their loss or due to the other side gloating too much. The trash talks won't really crossover to the new section as it'll still be relevant to the video to some extent and people will continue to post on the thread as they do now.
Same with trolling, most trolling starts with some smart ass taking someone else's suggestion or statement too literally and/or with a narrow mind. That wont stop, as people will continue to post their opinions and what not which others will see fit to mock on the same thread rather than on a separate thread or section where you are allowed to troll or w/e.
It'll certainly be entertaining and whatnot but the issues that exist now will remain the same.
At-least that's what i think o.o
