>If Youtube starts banning those accounts then they are effectively not allowing anyone else to join their platform

That's a huge if - one that Youtube probably is not going to enforce on new customers. The same principle applies to most businesses I know - a new account/client has X months to be profitable until they get dropped.

On the flip side, i've often stumbled (in the days where I was parsing youtube for side projects) on projects with hours long videos with 3 views - for years. My best guess would be that those accounts / uploads are what youtube is targeting, not preventing their new account sign up / new DAU drop.
