comment rating update?

I have been able to do some comment rating till a few days ago. I have VPN , and new accounts. I now can send the comment to the top, but after a few hours , thumb ups are gone and comment leaves the top 2 positions.

Has youtube done any update during the present week? Any help guys?

thanks

To my understanding you have to rotate the accounts if a account is flagged for spam it will no longer become a top comment for a while

Thanks kasuwell. Any more ideas?

Hey,
since there is a lot of people doing that , let's share our updates.
I have been having some success the past week, but nothing since yesterday , all my comments don't reach the top comments ( I'm using a custom bot to upvote ). Question is : Does it happen to everybody at the same time , or is it relative to me and to something i'm doing wrong ? I got a friend who started getting the same problem ( we're not using the same bot ) at the same time as me .

Also some of my comments completely disappear from the comments section right away , like it gets flagged a lot of time on the next seconds the comment is posted. This kidna beats me,i've tried vpns and proxys , same fucking result .
