Sacred Haven of Debauchery

You can write only fifty posts, but they will be on topic and useful.

Nonsense. No one knows what you wrote in those messages. People will only see the number "50". Besides, there is such a thing as moderation; you can't just post 100500 messages. It takes time. As for the database, who knows, a person might spend six months in WoW, writing a bunch of nonsense that has nothing to do with the game, and they'll just give them some rewards for no reason. Or, as your LightWarrior suggested, have friends leave. But these should be more or less decent relationships; no one will want to do such nonsense just like that.
But badges are really cool. It means that a person understands something about the game, and Wolf is wrong here.

I remember reading a thread about someone's unban; Morny was also there, and some people started attacking him.

I'm not surprised at all. He loves to stir up trouble
