I will admit, once or twice I have allowed a friend, or cousin, use my account for a day or two to try out the game with skins and everything. Its on days when I wouldnt be playing anyway, and the one rule I have is that they must state, and be open about the fact that they are not me. Ive only done it twice, one day each, but both people ended up trying to buy a subscription. (I say trying because they both had personal issues that prevented it). I really wouldnt complain if someone let their friend try it out for a day. And I DEFINATELY dont have a problem with father/son teams. God knows I would be extatic if I could get MY father interested in this... but I disagree with the multiple IDs. What is the point of having multiple IDs, if they cannot be on at the same time? I think it would only lead to spying and other unsavory acts.
