I was on the US server and was advertising that I wanted to spycrab 1 key. SMika sent me a trade request, then we agreed to crab 1 key. As shown in the video, I won the spycrab 3 to 1. He accepted the trade, but then disconnected from the server. I was suspicious that he was going to run, so I left a comment on his profile, saying I would report him if he ran. I went to eat lunch, and about 1 hour later, he had deleted said comment and had not accepted the trade. I left another comment warning him, then began to write this report.
Screenshot shows that the trade has not occurred.
