I had some bizarre experiences with both FB and YT content policing. First, I performed a Chopin piece on piano and it was instantly flagged by YT's content matching system. They reinstated it when it was evident from the video it was me performing. Second, I created a timelapse video and uploaded it to both FB and YT, using a classical music piece performed by US Army Orchestra (public domain) as background music. FB disabled it within an hour, after filling counterclaim they reinstated it for one hour and then suddenly completely removed without any chance to appeal. YT flagged it within one day and after appealing they put it back in a few hours and it's there since.
