Screenshots:
None, unfortunately.

Description: I run a trade server. A player,1029384756, came on and said he was selling Bill's Hat for 7 keys. I entered a trade with him, and he put up a Bill's, and I put up 7 keys. He then said he would accept but to give him a minute. I waited, and he came back, and said thanks for waiting, have some stuff for your trouble. He put up a bunch of random weapons, and lastly, switched out the Bill's for an Officer's Ushanka hoping I wouldn't noticed. I said "... Bill's please." and then he exited the trade, and so did I, to see him disconnecting from my server.
I have already banned him from my server.

I realize this isn't enough proof without screenshots, but I would like to submit this report anyway as a warning to other people who this might happen to. Quick-switch scams are common. Be careful when trading, and always pay attention.

Chat transcript (unfortunately, this does not include the trade chat transcript as I was not expecting him to pull off a scam):

Unfortunately, as previously mentioned, this is merely hearsay. Therefore there is nothing that can be done at the current time.
