Forum Trolls
They do things like downvote people to oblivion and make responses to legitimate threads that only serve to insult and address no points that were actually made.
This forum is terrible. It's so full of trolls that you cannot even begin to have a decent discussion on issues in or surrounding the game. That is my board feedback.

I don't even think these people play league. They just sit on the forums downvoting and trolling, offering nothing of substance to real discussions.
