I did extensive research on the background of this situation and it looks very clearly that the person who received the "empty" parcel actually didn´t even have the items he was trading the GGTS for... He has had several possibilities to show the red label on the package and the alleged letter of proof he got from the post office but he hasnt provided either info. All he has provided is a photo of opened letter which clearly is not marked damaged etc by the USPS. All we can retract from this is that he decided that its ok to scam in an international trade, he has sold and bought and traded domestically with no issues but maybe opportunity seemed too tempting to him.
The German who screwed me thinks the same thing, he has changed his forum nicknames and I've lost track of him......
