Story
My friend (TheRealDemoman) messaged me saying he whas gonna sell his beams honcho for a burning spartan and a SF RL, he whas very happy abaout the trade he whas gonna make, he got scammed though.
the scammer "quickswitched" the burning spartan with a regular one before my friend noticed.
Of true greedyness my friend didnt realise and still clicked accept trade.

So basiclly he lost 8-9 buds because the scammer switched his unusual for a normal hat, however i dont have any screenshots.
But my friend is a very good trader and he would never have sold his beloved honcho for a SF RL, i think that's proof enough.

Here's a discussion i had with the scammer on his tf2op trade:

first of all i scammed nothing! he agreed the trade and when he isnt checking the quality of the item then is it his fault!http://i.imgur.com/Yecpz.jpg

You quickswitched the item, you originally offered a burning spartan and when he wasnt paying attention YOU changed it to a normal one

Since he's offline atm (Problably studying/sleeping) you're gonna add him, wait for him to come online. Trade back the items and never do it again
