I wonder if there is a way, how to add option for community to ,add link for movie on YouTube". There is a huge amount of movies, which released mostly in the first half of the last century and are available on YouTube. Many of these movies are without licence or officially available. And there are just there - completely free to watch.
This article from 6th January mentioned some of them, the biggest one I would say, but as a member of this reddit group I see these movies nearly every day popping at me, and I think it is the easiest way how to see these hidden old gem. Most of us spend many minutes and hours trying to find them, because most of them are not on any streaming service, and it would be really nice to just pick one of them from Trakt Watchlist and go to watch it on YouTube, because it’s legally there.
JustWatch did some clarification about it TWO years ago, that it’s very complicated for them to verify if it’s still available or not, but I think this could be done just by community. It would be a big help for watching these old gems. Thank you for consideration.
