I think one action to take is to gather and show as many examples as possible, like she did on her Twitter account. In addition to discussing for pages after pages here, people can also retweet to amplify the message. Because it is the prerogative of those that sympathise with her, to point out hypocrisy of YouTube. They can't do as they will, punish selectively, and not expect public backlash, can they?
I also wonder if it would make sense for Naomi and other sympathetic content creators to make videos with different characteristics (same kind of demonetised video, but with the full spectrum of what YouTube deems questionable) to figure out more precisely where they draw the line, which would more clearly define YouTube's obviously malleable boundaries and paint them in a corner, for the purpose of giving people like her more opportunities to point out the double standard publicly. Just off the top of my head, the examples in this instance could be re-shooting the video with
- another cardboard clone that has a penis
- another cardboard clone with its nipples taped (I'm serious)
- Naomi in winter clothing
I know that this might come across as a stupid idea, and it shouldn't even be needed in the first place, but since all politics is shaped by public opinion, every weapon in our arsenal that can move it, even by a millimeter, should be used. It's hard work, really.
