If someone does not have balls to speak from their own identity then they are hypocrite.
That is not important. Because this is not an opportunity to reveal identity. There are many people who do their job honestly in this forum without us knowing their identity.
This is important in this case. You created this thread because you are butthurt and you want the manager to lose his reputation. You are butthurt maybe the manager found you cheating and left you a negative feedback. On the other hand you don't want to lose your chances to join their campaigns too if the cheating was not the reason. So you are hiding your main account.
We don't know if OP is not a trust abuser, scammer or competitor of the accused user. People are doing all sorts of thing to make others look bad, especially if that other is someone they do not like for some reason.
None of that really matters as long as those sock puppet accounts provide legit and quality evidence that support their claim but in this case OP failed to do that (at least regarding ban evasion).
I would not tell a word against OP if he was able to give good reasons to support his accusation. So of course I know none matters but in this case it does matter.
