I saw an article that says “only one Youtube account can be tied to one Adsense”. Is that true?
Also, is it true that if I link multiple YouTube accounts to one Google Adsense account, I will be subject to deletion of my YouTube account?
About tying multiple YouTube accounts to Adsense

Multiple youtube channels can be associated with one adsense, but if one of them is violated, or if the adsense violation is blocked, all the channels associated with it will be affected and will stop making money.
