it astounds me people think that they have a right to troll/flame on the forums. It really does. A forums purpose is for people to discuss the game. Out of Character does not mean 'acting a dick'. For a lot of people ' acting the dick' is actually in character, so they cant even use that argument.
At the end of the day - this is a free service, offered up by people devoting their time, money and expertise into it. If they want to keep the forums clean then so be it. If you don't like that, then don't post - go to reddit or somewhere to flex your finger muscles and prove how 'big and touch' you are behind your keyboard.
Flames serve no constructive purpose at all. They always end badly; they either derail the thread, get you banned, or more worryingly lead to personal attacks.
I will agree, that sometimes the best way is not to close a thread, but to delete the posts. And this is often what gets done but it can eb time consuming. With the amount of crap flying around the forums at the moment, I'd just close the threads too.
