Edit: The following has been a less common problem for the last several months, but I thought I'd leave it in so older replies will make sense: And why couldn't you let trolling GD threads get buried? They contribute nothing to the Dominion discussion. Just because they have the word, "Dominion" in them doesn't mean they can't stay in GD, or you'd be moving every other thread to the SR forum. At least read a thread before moderating it.
http://na.leagueoflegends.com/board/...2553591&page=7 <-- Let's go right to the page with a player saying he wants to try Dominion again because of the thread. In fact, that was the thread's purpose. Riot is killing its investment in Dominion by discriminating against GD-worthy threads.

http://na.leagueoflegends.com/board/....php?t=2193361 <-- This thread compares both game modes, which means it is not about Dominion only. It also served to get GD names talking to Dom forum regulars, strengthening the forum community. Moving this thread shows a bias against the mode that can only undermine Riot's commercial interest in Dominion.
January 20, 2012 finds: Some of these threads may have actually been started on the Dominion forum! Imagine that! Since I did not find them on the day they were posted I have no way to remember whether they had "moved" icons. Likely most were moved. I go back as far as Christmas.
http://na.leagueoflegends.com/board/....php?t=1652567 <-- A thread discussing why Dominion is a good game mode is useless when the only people who can read it are the ones already interested in Dominion. This thread was obviously meant to gain new Dominion players. The mods show animosity towards the Dominion game mode by moving this thread.
