According to QS, you edited your OP as soon as you got negated by Vod. You could have accepted escrow from the beginning of the trade. Sorry, my bad. But I presume, Vod noticed his unedited thread and took some time giving him -ve trust before posting there. I might be wrong though.

Never mind, this account is pretty new. So you can create another account and start trading in a serious way. But I think Vod gave that negative remark just to warn the buyers because, prevention is better than cure.

I would rather suggest you to sell that account via escrow and show him the proof.
