As long as you stick to Adywan’s donation model rather than Ivan Ortega’s you’ll be alright, I think, but generally getting money involved with fanediting is risky. I think a lot of the issue people had with Ivan was that he was framing it essentially as people paying him to ‘fix’ the movie, and he didn’t respond well to criticism in his brief stint on this website. It certainly didn’t help that his fanedit wound up being… subpar after he’d hyped it for years.
People use password protected Vimeo videos to reduce the chance of Disney copyright-nuking them. Clips of fanedits often don’t last long on YouTube if the algorithm picks up a few seconds of forbidden John Williams. I stick everything on Streamable out of habit and I don’t think any of it has been taken down.
