Sorry but that doesn't matter in the case of buying or selling accounts. Both should be tagged once it can be shown that the account has changed hands. As explained in the quote below. It shouldn't be a surprise to people even newbies on this forum that anything to do with Account sales for several years now results in negative tags. OP new this or they wouldn't have pretended it had been hacked in the first place.
Yeah, but there needs to be evidence of the account being offered for sale and transfer of ownership. I don't doubt OP's story, but I want to see proof before doing any tagging.
Apart from that the aggrieved party should open a scam accusation with TXID's.
