In the case of the car, you can still prove the fact of the violation of the law by the previous owner, and in the event of violation of the forum rules by the account - it doesn`t matter which of the account owners made it. Even if the purchase of this account occurred on the forum with transactions and full correspondence.
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!

How should the forum regulate the purchase / sale of accounts? Why do you compare federal laws and punishments with forum rules ?? Are you in the right mind?
How to regulate the purchase or sale, I do not know, but you need to punish the guilty! This rule should not have shades. What is the use of punishing the obedient at the forum?
