Folks say it was the same before TW2 release, so I'd wager to say it's... standard practice by now
This is true. There weren't very many members on the forums before TW1 was released but I still remember a few nay sayers even then. Before TW2 was released the forums had grown quite a bit and so did the level of BS. It's quite normal for internet forums to go crazy when a game is close to release so I hardly read or comment in those sections and spend most of my time in the community subforum.
