Thanks for the warning, I'm using yt-dlp so there is this risk that someday it will simply stop working. I'm currently always caching downloaded videos so that I will not have to download the same video more than once.

If we come to that, I'll definitely need to use a proxy service to work around it.

I've used ProxyMesh in the past for some WebScraping products (https://proxymesh.com/) and have been able to keep everything working for years so it may be a good workaround.
