As long these yt channel owners don't care about the security of their accounts,? more and more users especially newbies will get scammed sooner.
It's not easy which is like you're talking about
They just normal people who don't understand how to handle privacy and security correctly, and since they not a crypto user it's mean the hacker easier to phishing and hack temp. It's just like an investment advice, went some people from cryptocurrency trying to offering Ponzi/MLM into a non-crypto user it makes the target just like a fish and they falling to the scheme.
That's why they really easy to bait, cause they don't have so much knowledge, and they targeting a non-crypto user.
Some hacker pretending to be a business company who want to advertise by using their youtube and since the creator also need some money then he falling to the hack attempt. I believe why most of youtube got this scheme, cause advertises promotion could be their other passive income since Adsense really long to reach for the minimum withdrawal.
