Hahaha, I'm sorry but that is a bit amuzing. I mean, what did they expect? Kind of thought that would happen when i read the Rules for being on the server.
Small countries like Denmark tend to have a much more well-behaved population than large countries. I.e. they queue nicer, they are more likely to return something they found, etc. (game-theoretic research suggests that such a culture is a symptom of having a high likelyhood of meeting again - thus offering more opportunities to punish bad behaviour). That background might explain their optimistic expectations.
Possibly right but unfortunately anonymity turns people into total dicks regardless of nationality.
