When i thumb up my own comments manually with my 16 youtube accounts and become the top comment, they only stay at the top for about 2 hours? why?

does another comment out rate yours with more then 16 vote ups?

it has nothing to do with spam the new youtube alghorithm detects comments that are getting popularity. I recently did a test for a gaming niche. the top comment had 48 thumbs up but was made 2 days ago.

I started rating my comment when i hit 26 thumbs up. I immediattely jumped to the top. simply because that comment was old and my comment was newer.

If the video is getting loads of comments, the highest rated comments will be rotated. Only the newest ones will be at the top. They don't even have to have more rates than yours, it's all about the age.
