Scammer's profile link:http://www.sythe.org/members/462896-pursurtide.html
Explanation of the trade:I am selling a CSGO knife (http://www.sythe.org/cs-go-market/1905884-selling-safari-mesh-karambit-field-tested.html), to which this person replied to. He then added me on skype, and I asked for a pm, which is this :http://www.sythe.org/private.php?do=showpm&pmid=8783415.Assuming all was safe, and the fact that in his vouches he has reps from gold sites, I said ok, I will go first. After I gave him the knife he made me run around runescape saying he's in Falador, then in Varrock, in Lumby, and even once said I logged into RS3 by accident. This went on for a hour, and by this time, I'm asking for a refund. He keept saying, I'm sorry ill add money to cover up for your time. In the end, when I got super frustrated, he just deletes me from his contacts list.

Claims to have never spoken with you as he "never posted" his skype, yet you have his skype ID which when resolved, matches the same IP as his sythe account. He also pm'd me telling me the same lie. Going to ban him.
