If you've confirmed the trade, they're gone.

they are gone and you have scamsites in you name history and in some scamsite groups did you trade outside steam ?

Thats why you don`t use scam sites, your items are gone for good.

Your account is probably compromised because you have been using scam sites like the one in your name history. There is no such thing as scam trade offers if your account is not compromised in some way, unless you didn't adequately vet the trade offer in question.

Do these steps as a precaution but as usual, any items lost are not returned:-

1. Scan for malware https://www.malwarebytes.com/
2. Check that the email and phone number on the Steam account are still yours.
3. Deauthorize all other devices https://steamhost.cn/twofactor/manage
4. Change passwords from a trusted/clean device.
5. Generate new backup codes for your Mobile App https://steamhost.cn/twofactor/manage
6. Revoke the API key https://steamhost.cn/steamcommunity_com/dev/apikey (there should be nothing in the APIKEY)

Traded items away for a promise of something else that couldn't be placed in the trade window?
