This account is suspected by Steam Support in violation of the user agreement. Due to the purchase of stolen items and the use of third-party sites, the support service decided to permanently block your account. The possibility of transfer or sale of items from the inventory will also be blocked. The VAC ban will take effect within the next 6 hours and cannot be removed or appealed. If you want to save your skins, you still have time to transfer them to another Steam account. Regards, Steam support.
