Escape from Tarkov is one of the games where hardware ID bans are commonly reported. BattlEye can tie the penalty to the computer, so replacing the game account does not present a new machine.
The launcher can stop you before a raid loads. That early refusal, repeated on a fresh login, is the hardware-ban pattern.
The Tarkov spoofer is aimed at that HWID. It supplies a different hardware profile for the identifiers BattlEye-style checks read from the PC.
