If you suspect someone of cheating, hacking or tampering with the game, the best thing to do is to report it via our Cheating Report Form, you can contact a Community Manager via the Support Chat for further information.
Please do not accuse someone of cheating before you are certain that the person has in fact cheated. One of the worst things that can happen is to get accused of doing something you have not done. This leads to unnecessary confrontations and maybe anger towards other players where it’s not necessary.
Running into other issues, or do you have additional questions? Feel free to chat with us by clicking (?) on Challengermode.
