Count me in the same boat. Really don't know what to do next. It sucks when you know you are not a scammer , and show him every proof of it but he disregards it all making weird impossible theories.
Although quickseller is the only one to give you negative trust rating, you can see that you have also 2 neutral but bad ratings from highly trusted people so maybe quickseller is not so wrong after all?
Tomatocage did not add a trust-abuser because quickseller is not one, he would have negative ratings by now if he really was one
