Use a dedicated account for YouTube. How will they remove your emails if they’re on a separate account?
I use a YouTube channel account, which might be good enough. I’ve had one in the past banned and the rest of my Google account was left alone.
(I was only just getting into creating programs that communicate with online services and I hammered their API. My program didn’t have any checks and balances to ensure it wouldn’t go over it or to throttle back when the API endpoint attempts tell it to calm down. It only happened once but that was good enough to get it banned)
