@YouTube Some guy has uploaded a mashup I created which I was asked to take down many years ago. The form rejects the original URL as it no longer works - how can I file a complaint in this case? I have the all correspondence and the original URL.
It’s a mashup therefore I can’t declare it as copyright content. So this doesn’t help I’m afraid. But I did create it under fair use and YouTube requested the take-down. I complied, but the other person’s upload of my video is still there.
