Title explain itself, either remove report option from game or punish people who abuse report system.
Most of people I play together got banned because of upset report abusers who are only playing this game to abuse report system.
I am sure report system does not work on the situations it should. For example, reporting a Bot who runs same dungeon 24/7 never result in ban. But if you try to post something in chat such as guild rooster or raid recruitment you will get auto banned because of report abusers.
