I asked to spycrab a refined with him in a trade server today, and when he lost 2-3, he said "FUUUUUUUU" and left the game. I know that this profile is his, because as soon as I tried to add him to hopefully reconcile this before posting this thread, he immediately denied it and blocked me.

Also, more proof that the profile I provided is actually the scammer in question, sorry for not posting this in the original thread, I didn't think to post this right away but I feel I should do this now before he changes his name a few more times and makes it impossible to find out if it's him.

Without a screenshot showing the agreement there is nothing we can do, we're very sorry.
