I know according to a certain Oddworld forums rule that it is illegal to have 2 identities on this server. My question is this, How do you ever catch someone pulling an identity fraud crime and if so how did you catch the dishonest bastard? What is stopping me now(morals exempt) from saying my name is Mack yodelberg and I would like to register as a mister Sharky Mcshark?

Basicaly the admins compare the IP adresses of the suspects to see if they are simmilar. Other similarities also show that the suspects are a single person.
