I wonder if these type of trade can really go through?...
Let's say, the hero member quotes a price, buyer thinks is too high, negotiate a bit, deal turns sour, buyer keep on giving hero member negative trust comments (with multiple dummy accounts). Hero member not hugely affected, still looses out.
When the hero member quotes a low/reasonable price, gives the buyer an address, buyer sends bitcoins, hero member can choose to default (basically scams the buyer). The buyer has nowhere to report this, except giving hero member negative trust.
If a hero member contacts the buy with his true username, they have to agree on a price. If not, hero member is at a disadvantage. So naturally, hero member will not disclose his id until the deal finishes, but then the buyer will not pay until he knows he is paying for a real hero account.
Will there be a successful trade? We will never know
