I was starting to feel left out of this topic, but thankfully today I received my first yellow dollar sign...so I know that YouTube does in fact care about me too.
The video in question was two days old, had accumulated just over 5000 views, and was about explorer yachts. I never use curse words in any of my videos, and there was no questionable content.
The "request a manual review" feature was very easy to use, and the green dollar sign came back just a few hours later, so it was all a storm in a tea-cup really. I'm confident that the powers-that-be at YouTube will be working hard to make the algorithm more efficient, this whole manual review thing must be a nuisance for them too.
