Selling account on here is it and miss as some member that buy and sell again get neg trust and some don't I don't see how that works but it best to be in the save side and don't sell or buy it the best answer
Work on your english please. Translating with google isn't the best idea in some cases 
Usually if the sold account is identified it gets negative trust as a warning, especially if the sold account had green trust before. People are doing it to warn others that the owner of the account has changed. If you're selling you're safe in most cases. It's the buyer that's risking the most.
