Abiding YouTube but still demonetised?

You uploaded a YouTube video that follows fair use but still got hit with a copyright claim and your built up effort gets shot to nil?
Hundreds of hours worth of content gets posted every minute, every day. It’s impossible to stay on top of the mass of content being published.  Their solution : robots to scan your videos. Scanning for inappropriate or copyright material. It’s a good way of blocking users from uploading full films onto YouTube, it’s a way for musicians, authors, and other creative professionals to stop piracy at the door.  However doing this can infiltrate good intentioned users abilities to criticise, review, report, teach, or display research. 

As a side note, there is a large speculation whether or not YouTube takes away recommendation favourability if your video gets copyright claimed, if you cant make money from it, neither can the platform, and thats a speculation I prefer to believe and (hot take) also side with. 

If you were to make a 60 minute video full of slides, animations, transitions, etc.  This could take you a substantial amount of valuable time, and if you were to put on a 5 second clip from a film for any point you were analysing, but that gets flagged, in current day YouTube, all of that video is worth the 5 second clip, you get nothing from that video.

So, assuming that you are a creator with best intentions and following fair use (film criticism, news reporting, teaching, etc.) if the problem with monetisation is surrounding the visual aspect of your video, there are a few ways you’d may be able to possibly sidestep the stringent algorithm.

Of course in this scenario, you’re juggling the ability to make money from the content will directly impact the viewers enjoyment of your video.  
For instance if you were to stack all of these effects together. It’s completely uninviting and is clear what all the filters are being used for. Instead you could embrace a certain few of these to create a visual style, and by extent, to your channels identity.

Even if you are a (for example) lifestyle  / vlog channel, you should take good effort to review your content and focus on the background noise of the public areas you visit; car radios play copyrighted material. It is completely possible for demonetisation to occur this way too. 

These online platforms are amazing; it allows people to make money following the rules, but can be exploited by bad actors or plain misunderstandings. Be careful, smart, double check. Reminder : do not do this to exploit the system; only to add this to the content you are entirely positive are following the rules.
