Remove the report and karma system. Its broken (and useless)   what you can do with it:
• report other players for anything you want and lower their karma
• report other players for anything you want and cause an automated chat ban for 3 days
• make yourself feel better 7x a day by using your "power" to "influence" the game   what you can not do with it: • enhance player's game experience
• prevent people from being better/worse players than you
• prevent people from being rude or stupid     Remove this system of opression and stupidity and your karma shall rise.
