what does HWID spoofer actually do? does it bypass HWID ban? and make gametime account to unlimited?

and is there an option to adjust vehicle aimbot? I watched few videos and it seems like aiming enemy through cockpit.
I want to aim at vehicle itself, not a human inside it.
it's too obvious to kill people in helicopter everytime by directly hitting their head, not destroying helicopter itself. especially you're playing AA.
you know, I just dont want to make FF ban.
