@MZ the same happened to me i got negative feedback form quickseller he says that i m alt of tacoman without proving and i m afraid that he will give you the negative trust too i dont know what is wrong with him ..
He has put a neutral feedback in my account but I have no problem in it. I respect his action/decision on it. Although, it was never my intention, I will have to accept his feedback.
I don't know about your case, so I can't comment on it and also, this isn't the right thread to discuss it. On a side note, I find Quickseller's feedback as appropriate. I haven't find him leaving feedback without a reason. I think you should contact him to know "why". If you still didn't get a good reply, post in Meta. Remember, if you are really an alt of tacoman and Quickseller is able to prove it, more negative feedback will come.
Edit:
Given that more of the pages are dedicated to that discussion and that the OP is more or less solved perhaps we can just rename this discussion.
What shorena said is correct but I think creating a new thread will do nothing because many came and went down but it is worth a try.
BTW, @hilliarousandco, I know that there a lot of grey areas in real life and that money buys its way to the front of the line in a lot of cases but I do find it a bit ironic that the forum says "no ban evasion, that will get you banned even harder" but then says "well, buying and selling accounts isn't exactly cool, but what can we do about it?". I guess I find it funny that restricting account buying and selling is considered unenforceable and therefore acceptable but ban evasions are serious shit.
It isn't enforceable but I am pretty sure it will reduce account sales.
