It is not illegal to buy or sell accounts but it does not matter, the point is that he was scamming on his alt account and now he is complaining that he got negative trust on this other account which now makes no sense.
isn't it always against rules to buy/sell/trade forum accounts?
It isn't on this forum, though I find it extremely sketchy.
that's odd.
people will only have to invest some time and they are good to go.
they can even become hero, get positive trust and scam escrow
You need more than a year for a hero account and you wont be able to escrow even if you have one, people buy accounts mostly for signature campaigns or because they got negative trust on their other accounts like OP did.
