Essentially, I was out on OP looking to buy some of the new trading card beta passes. I offered a craft hat, and was quickly added by the poster. Soon after, I was added by someone named "Meowzers". I asked him what he wanted, and he replied that he was going to sell me the pass. I told him he wasnt the one I offered it too, and I asked if he was hijacking. He replied quickly with "Yes" and that it was his business and that I should grow up. I clicked his profile to snap a picture, and then completed my trade. He told me I needed to grow up, so I went to his profile to unfriend him, when lone behold, he had changed his name 6 times to cover his tracks and had changed his picture. It also shows that he still has the same picture and name in the trade chat, even though hes updated it.

This would be something to report on Outpost. Trade hijacking isn't considered a scam, it's just against the rules on Outpost. Thank you for the report.
