Let me tell you a story of something that happened in another forum I frequent.
Person A started an LGBT thread. It got quite a lot of discussion. After only being up for 2 days it reached about 35 pages (Some of which was slightly off-topic, but over all nothing was wrong). Then person B came in and started ranting (I say ranting, but I really mean spamming) about what a waste of space the thread was, and that it shouldn't exist because it supposedly had no purpose other than to let people talk about sex (Which isn't against the rules anyways). Then he had the gall to claim that the thread was in fact offensive to straight people because it excluded them from the discussion topic. After 5 pages of this shit a mod locked it because of "too much off-topic discussions and arguing."
So that ONE PERSON got an entire (And quite popular) thread locked because of his individual childish behavior. Never mind the fact that the mods simply could have given him a warning to get him to stop. No no, they needed to lock the whole fucking thread.

Tell me if you want to hear more stories of bullshit mods. I've got a couple lined up for rainy days.
