There are no social limitations here, only optional incoming filtering. There are no game moderators, no temporary banning, and no global muting. There is no world chat channel.
Rule 1: There are no rules!
Rule 2: Solve your own disputes!
Someone bothering you? Take care of it yourself!
It is because moderators are basically the worst type of parents. They
are like parents who promote immaturity in their children by not
allowing them to solve their own little disagreements.
Another reason is the advanced filters. If someone is annoying you with their talk, filter their chat out.
If someone steals your items, it's not against the rules, steal them back, or worse.
Another reason is that player organization is promoted. This means that you are encouraged to start a local police squad or a local military to defend each other. Also, those with the power make the rules. This not only adds that extra layer of intrigue to the game, it also ensures that everyone gets to play, no matter how socially inept they may be. If you want to 'ban' someone from your town, you have to post guards at the gates, and start patrols out looking for the person in the city, then you throw the person out, into the lockup, or any other kind of cruel punishments.
