Just to make it clear: I obviously don't mind theymos expressing his opinion, I appreciate it. I dislike the way it was done. He can blacklist users (and preferably explain the decision) if he wants to. Or post his opinion publicly and let everyone make their decisions.

And no, it's not the same as someone else (e.g. Lauda) campaigning for inclusions/exclusions. I could tell Lauda to fuck off and nothing would happen regardless of what the conspiracy theories would lead you to believe. I don't think many recipients of that PM would feel the same way about a request from admin. Perhaps my reading of the situation is flawed. Let's hope that's all there is.
