Why do we need forum rules, if you can always come up with new ones? Are you friends in your mind? There are clear rules, ban it for the culprit! Ban in this context, this aiding in fraud! Friends, I thought we had a forum here, not a fraudulent club!
You can not kill the real owner of the car, for the sins of the previous owner! Killing the real owner, you become the same criminal, the law in this respect works for all equally.
You are not in your right mind clearly. Let me get this straight to you because Ddmr's way on telling this with a car as an example is kinda has a loophole to counter. Buying and selling account is not moderated by the forum, so why the hell does forum should look into the matters that is not moderated by the forum? Maybe banning a scammer can be done in this case, but repairing a broken thing you bought is not forum's responsibility, instead you should complain to the seller who sold you that account.
When you buying a second-hand car from others and you find the car won't start in the next day, do you complain to the car dealer or the person who sold you that car?
