i've got six primary comments left to remove, although i'm realizing i've accidentally deleted a few. the system makes even less sense than i thought.
(1) if you delete a post on your google+ page, it removes it from the youtube comment section and vice versa.
(2) but if you reply to the post on youtube, you cannot access it from your google+ page (and similarly, if you reply on google+)
what's worse is that the hyperlink to youtube seems to break when you have a certain amount of comments. the comments are there. but, you need to scroll through thousands (literally - in fact, tens of thousands) of posts to find them.
so, i deleted a few comments from my google+ page, thinking that i had the pages open and i'd be scrolling through to find them. but, this resulted in removing the comments from the youtube system. they're gone.
whomever created this system was an incompetent idiot. it was a perfect system. and it's been replaced by something that could only be described as irrational.
but, there's six left. then, i need to clear my watch history post-by-post to try and find all the conversations that i had - and are still there.
