For Indirik's post multiple characters can do the same thing except for the false family thing.
And that's it, right there. Games—especially those that involve many people—have rules, because rules allow people to establish a certain level of trust. Otherwise, the game doesn't work. A person with multiple accounts who is not abusing them for the advantage of any particular account cannot
prove that they are not. It immediately arouses a suspicion, borne out by the vast majority of past examples, that cannot easily be satisfied.
In other words, it isn't a rule that exists to punish players who love the game so much that they want to experience more than the mechanics allow for. It's a rule that's designed to protect the social compact that the vast majority of players agree to, implicitly, when they play a game with strangers over the internet expecting a fair shot.
