Who said that it is allowed. Just because some members do this, it does not mean that buying and selling accounts is allowed. They should be banned, only red trsut is not enough for them.
We don't ban the selling of merit, people just frown upon it, the same way they do the selling of accounts. An exactly as owlcatz said, there is no way to enforce any rules against the sale of accounts. If we ban the 1 in 10 we catch, the 9 that make it through the cracks will be able to do more damage to people who don't consider the possibility that an account has been sold, because its not allowed. Its more productive to just tell everyone that it is openly allowed, and to be vigilant.
Let me ask one question in connection to this thread, if selling account is not allowed, (though many do it), is it okay to pass an account to any other relative/s?
No payment exchange had been done, is there a process wherein you will inform the admin about this thing?
??!?
Once again, account selling is allowed, so pass it onto your mailman if you'd like, you don't need to tell the admins.
