Report for scamming

This guy said that he's selling DPs so i offered him RP. He said that he wanna make sure that i won't scam him, so he said that i give him 50rp in advance to gain his trust. We have a good deal but he didn't came back. After 20mins, he's on the game and forgot our deal. Here's the screens. Hope you take some action. Thanks!
