So, how do bans work?

If I decided to try out some cheats on Warzone, how could a ban affect my other accounts? Will my other Blizzard/Activision be permanent banned if the account I cheated on receives a perm ban? Will my PS5 CoD account be banned?
How extensively are IP bans used? Do I need to be utilizing a VPN?
If I spoof my HWID before ever using cheats, is that sufficient to not receive a HWID ban?
Thanks

If you wanna secure your hwid then yes use a spoofer especially if cheating, cheat wise if you wanna last go with mobius. Spoof wise you can go with ghost aim or Sync. Account wise if you get permed on PC and use said account on Ps or Xbox the result will be the same you'll need a new account

They hardware ban your computer and perma ban the account you're cheating on. Why would you be worried about an account you play on via console? Are you cheating with this account somehow? Maybe an unlock service?

If you use a good cheat undetected. You don't need spoofer. Spoofer are always detected some how.
Don't cheat on your main account. Never.
