Three times now YT has either refused to upload or has rejected videos I have created. None are duplicates. Most are a combination of a new, introductory video followed by a video that gives some sort of example. Many like this have been accepted, but now three in one month have been refused and all come with a notation that if I remove the video, it cannot be reused. No real reasons given. This wastes a lot of my time and is very upsetting as if I don't know what I'm doing wrong, I cannot fix the problem. YT is not being fair, and I'd like to know what I can do to stop this.
