orcishgamer: He's an official representative, his job is to not piss people off, he pretty much has to leave if someone throws a fit about how inappropriate it is for him to post here, yeah, he pretty much can't stay here, it's not petulance, it's his job.
Was this the "Amazon representative making appearance on GOG" case? While I don't remember saying anything back then and didn't mind it _that_ much, it still felt kinda odd to me. After all, Amazon is a direct competitor to GOG. I would feel the same way if a DotEmu, GamersGate or Steam representative came to GOG to "answer questions about their service". The appropriate place for replying those questions are in each company's own forums, IMHO.
I was thinking that more as how the GOG staff would probably feel about it (but would fear to complain about it at least publicly, in order not to get any backlash from users), not so much how I as an end-customer would feel about his presence. After all, I was interested to hear a semi-official answer to the question "why is Amazon Digital so US-centric?", even if it was on the GOG forums.
Same way, if a GOG representative started to make appearance on Steampowered forums in order to market their competing service, I could understand even if Steam admins would ban him from the forums. This is business, after all.
In a nutshell, I felt the Amazon rep crossed certain line when making the appearance.
