they do take action against cheaters there is proof within these forums with many people comming on and asking for their accounts unbanned etc.
they have also said that only levithian is working on cheaters for the time being so things will take longer to be actioned.
they have also said they are concentrating on a new cheat detect system that should come into force with the new grand arena stuff.
end of the day if levi is getting 100 accounts daily to check they aint gonna get through them.
give them time and if you have reported said cheater with proof then DO NOT report them a 2nd time as it moves your report further back in the queue.
they will not tell you what action they are taking but rest assured if they are caught cheating action will be taken in due course.
in the meantime knock the cheater back as much as you can and wear them down until they back off.
