One thing I've noticed on every game forum that I've ever been on(I need to stop spending so much time talking about games) is that there are people that log on just to bash a game.
I'm not talking about pointing out weak points or talking about things that they feel should have been done, after all, no game is perfect and devs need feedback. More than once I've complained about Oblivion's Main Quest and the level 20 limit that Fallout 3 used to have.
I'm talking about people that seem to have some kind of vendetta or grudge against a game, and get on the game forum to knock it at every chance they get. And they can get mean at times, especially against people that enjoy the game or disagree with them. When I was playing Star Trek Online in it's infancy I actually saw death threats in their forum.
Sometimes they write long walls of text to state a minor point that they have against the game. I've seen it in every game forum I've been in from Star Wars Galaxies to World of Warcraft to Oblivion to Skyrim. I can only imagine what the Call of Duty or League of Legends forums must look like.
What do you good people think?
