Mixa12 seems like of their main account that was used to buy that account from someone and sell scam and sell the account to me
might be he have more accounts, if someone is good at finding such stuff can help and find other accounts of the user.
I can tell you one thing for 0.14 BTC your account is not the lord who will not sell. The minimum price of 0.22 BTC your future.
I buy and sell accounts. When I buy, I check them, and sell more! What happens to them then I do not care.
