Beyond the Customer Relations team our Content team is constantly looking into ways to alter the game itself to reduce the ability for people to cheat, for example the recent creation of the Bank PINs and the essence mine changes.
The main source of information on rule breakers comes from you - our players. Every abuse report we receive is actioned accordingly and will be recorded on the offending player's permanent record. Processing the abuse reports cannot be done instantly, and action taken happens behind the scenes, so we cannot guarantee that you will always see the offending player being removed from the game - however the good news is that we are now more successful than ever at processing abuse reports quickly and seeking to educate players. Those who are not willing to be educated are removed.
So if you are an honest player, you can do your bit to help all this by sending in Abuse Reports whenever you see someone breaking the rules. You can also help yourself by keeping both your account and your PC safe - advice on how to do this being found in the Knowledge Base.
And if you're a dishonest player you can do your bit by stopping breaking the rules now.
We will find you and we will ban you if you don't play by our rules.
