According to the VP of Product Management at YouTube, Ariel Bardin:
“We may remove a channel’s eligibility to be recommended on YouTube, such as appearing on our home page, trending tab or watch next”
YouTube has outlined the following 3 steps:
1- Premium Monetization Programs, Promotion and Content Development Partnerships
They may entirely remove a channel from Google Preferred and may also suspend, terminate or remove a publisher’s YouTube Original.
2- Monetization and Creator Support Privileges
YouTube may suspend the adverts of a particular channel and could also remove it from YouTube Partner Program including all the support.
3- Video Recommendations
The video-sharing site may also diminish the visibility of a specific channel from its ‘watch next’, ‘trending’ and ‘home page’.
