The cheaters/hackers/offenders are in minority. And we have an Anti-Cheat system to take care of them. But sometimes it doesn't detect them. So we have other measures to take care of them. You can report offenders via " /vote nickname " command in battle. Or you can record a video of offender and report him. More information is here: How to report a violator?
