I just got kicked

[Sida]

Something just occurred to me. This "person I've never seen before" might have just as well been the main character of someone who had recently been playing their alt a lot. So while you had been nice and helpfull in their presence earlier, you seemingly suddenly turned (seemingly) annoyed/hostile. As for the trade down as a concept, there's nothing against it in this game, by the way. It's not made easy, true, and if it concerned large amount of money, shards or such, it might be on the suspicious side. But if someone just wants to move random selection of inconsequent gear pieces on occasion there is no cause for alarm. Also, the people who report someone are not told about the outcome of the report. Additional information might be requested if necessary but not always. Its totally possible however that GM had contacted (or even punished) the guy you reported. Getting or attempting to get someone punished for no reason tends to be perceived badly.
