Impersonator's account:

(My personal main suspect) Main account: https://steamcommunity.com/profiles/76561198085893648
He has the exact same name as the names that he used in his Alt 1 account, before he cleared all the names.
Coincidentally, the PA Arcana, just magically appeared in his inventory with those exact stats, a few days after the scam.
Full unlock, 104 Assassination Score, 2083+ Kills

This is not a random person, I've tracked him down using the tools that I have available.

This user impersonated me and stole my friend's expensive Dota 2 items:

• Codicil of the Veiled Ones (11,85€ on the market)
• Exalted Paradox Manifold Arcana (26,07€ on the market, but it was FULL unlocked, which is worth more)
• Auspicious Nyx Assassin's Dagon (7,19€ on the market)

Total loss: 45€ +

He talked to my friend and scammed him of his items.
My dumb ass friend who isn't an experienced user... fell for it.
In spite of all efforts that Steam made to protect him, he still felt for it.
In order for this scam to work they had to be friends on steam for 30 days.
The trade failed via Steam, so he asked him to log in to Dota 2 and send the items as a Gift.
