and that is what makes it sad. - you justify bad behaviour by saying that reality is bad behaviour. so your own behaviour is victim to your own self fulfilling prophecy instead of trying your own very best.
if everyones attitude was like the one you described - it is no wonder things may go downhill - while at the same time everyone complained that things go downhill.
but you may answer that question:
would you prefer much more restrictions that may assess if someone is capable/worthy of wielding greater power that affects other players? - or do you prefer the freedom to (mostly) do what you like - for the good and the bad of those you play with.
when you offer freedom, you will always get those that exploit it. - when you restrict them more, you may achieve a more homogenous enviroment at the cost of chances to evolve creativity.
just to comment on that before you may choose to reply or not. restrictive systems have been viewed as something that is holding players back. ( see closed factions ) ... the discussion is fairly old indeed. - battleships come to mind and how freely they are available ( or for that matter ... even VHF )
edit: i do however give you that ... maybe i am - as i may call it - a bit more idealistic than you are and not stuck in a downwards struggle regarding disco as a cesspool of bad behaviour and trolls. who knows - maybe you are right and you, the players, can really not deal with ingame problems yourself anymore and need to be led by the hand.
