thats only half true, once you get a certain amount of posts under your belt, you can be a dick and people will call it funny, ie: mike
I doubt it has to do with the actual number of posts.
Once someone has earned (or gained through blackmail) a certain amount of respect, people will generally overlook some dick-headedness.
This is not a permanent condition. After an amount of dickheadedness, the respect will start to dwindle, and thrust a once respected poster into twerpitude.
