Tagged. I know it's not worthy to tag a newbie account offering Bitcointalk account sales, but there should be a warning that would be read by others. Likely he will create another account to advertise his account sales. We can't prevent them from actually creating multiple accounts. Most likely he is a scammer, asking for upfront payment. And other accounts would be hacked or botted. Everyone should avoid dealing with that guy.
Yes, now the account has got tag 2 from DT and it seems meaningful enough to make people think before making a transaction. In addition to asking for an upfront payment, I think without escrow it will also be very dangerous if someone is interested in buying Twitter or other accounts.
But I was totally shocked by the price of the Legendary, $1500 would someone really want to buy from it and entrust it with that kind of money?
