There are some clans in this game that have GM buddies so don't bother reporting anyone from the clan Sinister for cheating. The GM will start asking you questions on why you thought that person was cheating (and then let the accused know he made it obvious) and then tell you it will be investigated. Normally when you report someone for cheating you will just receive the message "This will be investigated". Funny how its different for certain people. Just a heads up so if you ever see these guys just let them win or you will be on the GMs bad side that they are friends with.
