So... it turns out Mods can kick you from servers for anything they consider 'misconduct' at least that's what these mods told me.

I was getting kicked randomly staring soon after I beat one of them in a joust. Eventually they just banned me outright for complaining.

*Shrug* If someone can pull up the rule book that said "making a mod feel bad gets you banned" then I'll sit down, but otherwise I'm convinced that this game is full of mods on power trips.
