I made a comment less than a week ago where I stated my opinion on Justin Bieber’s formulaic success, which immediately received more than 50 thumbs up. When it hit 60, it was automatically removed. Its no secret specific performers/products have paid promotions to youtube in order to target market members of youtube, which is a very lucrative avenue of their business. If you happen to criticize one of their lucrative partners or products, will youtube have an admin remove a well liked comment from the top comment section? My comment was removed not only from the top comments, but from all the comments on the page. Would youtube monitor and remove comments based on contractual obligations with their paid partners? Smells fishy, but I figure I would ask the community…
Not youtube itself however the uploader can remove comments for whatever reason.
I doubt youtube itself would remove comments from videos. However I would imagine the owner of the justin bieber video would remove comments that don’t support him.
