Most likes I've ever seen anywhere on Youtube.

These likes date back 8 months ago, I was wondering how long do top comments stick. When I increase my comment to top comment after an hour or two it disappears.

Are my comments being flagged off? Or is it just that if a comment doesn't get rated over a period of time they get removed and new comments with likes get bumped up.

Edit: My comments don't get out rated. New comments that take it's place are a lot lower.

look at the upload date...
look at the views..
look at the channel...

one of top subscribed (real) channels on youtube.
they tend to do that.

BTW if you notice kyle uploads his video and disables comments after X amount of days so if you want to post a comment after that you cant. all your left to do is thumbs up a comment you agree with.. makes sense.

If anyone user gets more thumbs up you will be bumped off the top comments.

That video has comments disabled, The only thing people could do is like, dislike or flag them, None of them are spam so no one even thinks about flagging them.

Only way a top comment goes down is if it's getting flagged down, down rated or removed by uploader.

well i know him and all those likes come from his twitter followers
