If you have your YouTube comments set for you to approve them, might want to check them.
I check every day but this morning, there were comments as old as 3 weeks waiting for approval.

Hi, thank you for your tips. This would be helpful to our valued customers who have accounts on youtube to post their drone work. Thank you for continued support.

It was a recent discovery for me as well. Whatever the algorithm YouTube has put in place to filter the comments (most probably spam), it is definitely not working well.

Search filter has been broken since the New Zealand shooting.
YouTube claims they are "fixing it" to where violence cannot be searched.
Temporary fix is to use Google search engine and filter video results there.
But that is lame.
Google is YouTube
