Banning the account transaction will only make this kind of transaction to operate from underground which makes the transaction hard to be tracked. By not banning the selling or buying of the forum account this actually have more benefit since all the sales of the account will be made in public
By outlawing armed robberies, we only force armed robbers to "operate from underground which makes the [armed robberies] hard to be tracked."
Something like that?
Besides, who would want to track upstanding citizens dealing in forum accounts???
