Honestly, I'm a bit concerned here. YouTube's automated tools aren't the greatest at flagging content, and quite a few videos have been mistakenly marked as for kids/infringing copyright/being in the shorts format.
The fact this status can be removed by the uploader certainly helps fix this issue, but then it feels like something any good conman will be able to work their way around really easily. Make sure the video doesn't blatantly use any tools that YouTube identifies as AI without extra changes, then put the video unlisted or private for a bit to see if it gets caught.
But something like this is needed. YouTube is currently overrun with AI generated videos, and the current systems make it really easy to hide that fact from 99.99% of viewers. It just needs to be done in such a way that:
A: Innocent creators aren't wrongfully screwed over B: Actual liars/scammers/grifters can't easily work around it.
