Guys I'd like to notify everyone that there is a new scam method.
People got smarter so the scammers have to use different methods. I just recently almost got scammed by a guy called marios#2955. The method he used was to ask me first if the items were duped cause he didn't want to be scammed. Then he told me to prove it by dragging the items to the 3rd and 4th slots to make sure they are real. What I did was right click which is the way to not drop items if he closes the trade, and I placed a gem on the 1st and 2nd slot so I could right click my items onto the 3rd and 4th slot. He told me that wasn't legit and that I wanted to scam him appareantly.
I hope this will help you guys watch out for these guys cause getting scammed ain't fun.
