They claimed I was being impersonated and scammed them. Then they said I needed to talk to a "Valve employee", either through steam or discord (should have been my first red flag, the second red flag was the poor English). The "Valve employee" said I needed to trade my "recent trades" to a "program". It wasn't after I traded that it was scam. The good news is that they now have a trade ban (and through some help, found out that they live in the Philippines, and local authorities were informed).
