I wonder if that's something that can be addressed by embedding the right metadata into images/videos? Most people don't bother even checking e.g. Exif data (let alone stripping or otherwise altering it) when reposting content they find online.
I can't speak for every platform but when I was working with frequent photo posts, most in-camera or post-editing metadata was stripped out on instagram and facebook. Some smaller sites like Gab didn't seem to mess with it as much, but the bulk did. I wouldn't be surprised if all of the other big ones did, too.
It was incredibly disheartening to have no recourse to attribute my own work, other than to smear some gross watermark on it. The automatic removal of that metadata, along with AI image generation, are some of the reasons why I gave up on the hobby entirely.
It's incredibly hard and stressful to derive any sort of pleasure or interest from something when the second it's exposed to the internet, any sense of humanity you tried to attach to it is stripped away, burned, and commercialized for the monetary benefit of some ethereal financier. It's the sound of an invisible vacuum cleaner, whisking away any sense of joy or life you wanted to share with the world for common love; the death of sharing. For-pay hugs.
