Hi, I have made couple new characters and thus I met alot of bots along my adventures. I have learned to quickly see trough bot programs even when they try to act like players and have human like names. There are some maps that are extremely often used for botting, specially with certain classes. I really recommend that you start to give considerable rewards for players who wanna help to ban bots, TP or such. For certain amount of succesfull bot reports in row u get amount of TP.
But even more I suggest that u just send GM’s to visit these areas once in while or some1 else who can instantly ban these bots. If u dont have enough persons working I am pretty confident there are alot people ready to do this just for a small fee. For example me myself.
