One of the problems I have with the demonetization system is that users don't see how unfair and wrong it is. Only the creators see these things.
I am offering support for all members here.
Once a month, I will put a video up on the YouTubers Union channel, with teasers for unfairly demon'ed videos, and the links of course.
So if you have "yellow dollar" videos that you feel should be "green", make a ten second trailer and send it to email@example.com, via WeTransfer. Feel free to add a bit of explanation if you want. Include the link to the full video.
This will give people a feeling for how bad the situation really is.
I will release the first video after I have ten examples. I won't monetize those videos.
