I hang out in lots of different places that have very different feels and attract different kinds of people.

Some places I hang out have people who have reached the consensus that "Warezing" is normal and fine whereas other places (like here) it's considered stealing plain and simple.

What creates such communities? I know the people who run sites that have people who seem to have no morals and they themselves are very moral, ethical people yet their sites are full of petty criminals.

What creates a net society of upstanding people? What creats a net society of people who are generally the same age despite having never met or usually devulged their ages?
