Have you messaged the runner about this? You could message them both on-site and off-site. They might be able to provide clarification. - as they moderate the game. They were also last online today, meaning they're still active and might respond.
If they do turn out to be a cheater, then the site does permanently ban these people. But this is a hard thing to prove when you're accusing the only super moderator of cheating in their own game.
