how to write to a developer

Yeah that is not what happened. I specifically told you many times that the person might be cheating but I have no idea. The problem is the proof you had wasn't proof at all. The only thing you could refer to was his fleet GP. I told you to ask the fleet discord server to see if they think it's possible and you never did that. You even saw another person doing the same thing in your fleet shard and decided that maybe it's not cheating.

The reason you were kicked out of the server is because you started blaming myself and others as covering for this person (even saying its one of our alts), when all we're trying to do is make sure some one is actually cheating before labeling them as one. The only evidence you had was GP.

Also, this person no longer playing doesn't mean they were banned.
