We all know accounts are ALWAYS recoverable, but what if the rules said that accounts can only be trade through Paypal that way it protects the buyer and the seller?
I really would prefer not giving somebody an account with no recoveries or email registered with all previous information to be charged back on paypal, it has happened to me before and the person successfully kept both the account and money. If you buy off a trusted member and pay a little more you will most likely have no problems. Also I'm sure its not allowed to suggest something which alters somebodies use of the market for trading, and some people don't have a paypal to use as theirs have been locked or other problems such as underage.
I don't think you should be forced to buy accounts with paypal and nothing ells. If your worried about chargebacks/recovering use playerauctions or just don't buy accounts unless it's from a highly trusted user.
