Does the youtube upload have print-sourced audio? Could be that, and the scans, don’t quite match the contentID enough to get an automatic match. It’ll take someone from Disney or Fox flagging it manually.
Edit: Oh, now I see what what quote from Dan whoever is saying. I’m not sure it makes sense or that I believe it, though. Anyway, a youtube content strike isn’t the same as a real CDO. If someone from youtube accepted the uploader’s rebuttal and left the video up, they probably didn’t do their job properly.
