Many game discussions are filled with people who do not own the game and are just trash talking games to bait arguments. One way to combat this would be to restrict players from posting on the discussion forums until the player buys the game and has owned it or played it too long to refund the game. I think very few "trolls" would buy games just to start or respond to threads trying to pick fights with other players.

Also steam could develop ai to identify threads by trolls earlier, that a human moderator could verify, to ban these players faster and for longer durations. Maybe with a three strikes out rule to perma ban them from all forums.
