Well, looks like a trade deal going sour. I dont wish to be involved in a your arguement but i was wondering what MD has set up to prevent scaming? I cant think of anything...? So, everyone should really be carefull when they trade things, especially if youve worked hard for it. To be safe you should record the whole trade to be safe (For example using screen recording programs), atleast to be able to send some proof to mur who could in theory reverse the trade. That is, if your were scamed. Tbh I dont think mur can do much without hard proof.
On another note, there are scammers out everywhere, not saying i know any personaly in MD, but just be carefull;)
