It doesn't matter whether or not people know whos who. It doesn't matter on defences. It doesn't matter how much group effort you put in. Posted earlier people refer to bad apples and that is true. People are ruled by greed and power not by government. Even if you get a good some of people to live together how long will it last till someone pissed off and decides to destroy the town? How will you eve control these mass amounts of people from doing stupid things? You can't, your best bet is to live with people you know in real life but even then thats risky.
This super power idea is wanted yet there is the minority in this game that destroy these ideas as well as possible good things that could happen in this game. Read the politics it is blankly sad what this game has turned people into. Every thread is like a Colosseum of Rome in which people kill for "fun". It is those people who make this idea impossible.
