Relapse

So I have never cheated on modern COD games on pc only on previous console versions via modded consoles. But I have cheated heavily in PC games like CSGO,Rust,R6, and Tarkov. So I am a little unfamiliar with the activision ban process. For example in CSGO if you are using an UD cheat and not raging(only using esp and maybe anti-recoil) you can go a long time with no ban. Is it similar in Mw2? And if you do decide to rage (obviously not on a main account) what’s the ban time like? Additionally when you do get banned for raging can you buy a new acc and start all over again provided you are using a spoofer? And how do shadowbans work? Also If not cheating on main account is there any collateral ban risk shadow or otherwise? I know this is a lot of questions but I like to be as informed as possible lol.
