So, yesterday I bumped the trade of my unusual, and I got 2 f requests automatically.
The first one was a obvious pisher, private profile, level 0.
The second one was very legit, level 10, custom descriprion and other stuff.
He asked me the price of my unusual. I said 2 buds, to try getting the most profit. I thought he would get lower, but he accepted the price.
I was surprised and happy, but when I checked his bp it was worth 0.1 crap.Only untradable halloween hats, crates and other f2p stuff.
I asked him about it and said that he would get the pure from his friend. It was all normal until he told me that he wanted to check if the hat was duped. He asked me to trade it to a trusted friend, but It reminded me of how my friend lost his 7 bud unusual.
It happened the same thing to my friend, the scammer will ask to trade the unusual to your friend, and then he will change his name into yours and trick your friend to trade it to him.
So yeah, don't do it.
Since I knew what was his plan, I told him that I knew his game, and he blocked me.

Also, the comment section of this guy was filled up with +reps, but I checked the profiles of the commenters and they all had crappy bp like his.

Here's a part of our chat

Zhatar: Take your time
BOOMBASTIC: erm
BOOMBASTIC: do you have a trusted friend online at this moment?
Zhatar: Why?
BOOMBASTIC: well, i wanna buy your hat for 2 buds, and i wanna check if your hat is duped or not
BOOMBASTIC: and
BOOMBASTIC: i checked backpack.tf already
BOOMBASTIC: so yeah the purpose is to check if your hat is duped or not by trading it over to your friend so i can check if your hat changes to duped when you traded it over
BOOMBASTIC: because some unusuals has a random chance of becoming duped when traded
Zhatar: Hahaha
Zhatar: It happened to my best friend
Zhatar: same thing
BOOMBASTIC: ?
Zhatar: and the guy who wanted to give him pure
Zhatar: changed his name
Zhatar: and stole the unusual

Somebody please make a video about this, everybody needs to know!
