This user named "just a demo" Added me and wanted to buy my Baloonicorn #7 with 45$ cash. Thoguh hwe was nice, I could tell between his join date , private BP, and method of trading, as well as his "rep" in the form of ebay rep (which could be some random user for all we know). I took all these into account and was planning on getting a middleman. Sometime later, a person told me he was recently scammed out of a white Bills by the same user, I made this on his, mine, and the entirity of the steam community

To get this user banned , the person who got scammed is going to have to provide a screenshot of his inventory history & his pp account. So Sr can verify that this user did actually scam , because there is No proof at the moment.

I was just scammed by this user. I lost 2 copies of Just Cause 2 and a Fast Learner, which I planned to receive $22 for. I admit that I was being extremely foolish, and I should have checked his reputation first.

Here are pictures of the Steam chat I had with him:

The ebay link he provided was simply to an unrelated user's seller profile, and seems to be pretty obviously not him. I was foolish and just glanced over the profile, and did not notice this at first.

Here is a picture of my Inventory history:

The most recent two trades are those with this user. The pictures do show his name as "no s✿✿✿" because he changed his name after the scam happened. I cannot view his inventory or add him as a friend due to his Steam privacy settings.

I can testify that this user did actually scam. If there is any other evidence that I could provide, I would be happy to find it.
