If you have an issue someone is cheating, you can report it on the website.
In this case, you have to follow this procedure:
1. Follow the target player in spectator mode and take a demo. See Record a demo.
2. Upload your demo to the website by using our file uploader. See Upload your files.
3. Fill in the Report a player and put the link to the uploaded demo on it.
Please be aware: Do not call someone a ‘Cheater’ or ‘Hacker’ during a game.
If you decide to say that in chat, you are only helping them to hide from the admins and avoid a ban.
Of course, we have zero tolerance for cheating. So once we find out someone has done, we kick him/her out of our server by all possible means.
