Run this by those making the films and those who hold the copyrights - pretty sure you'll change your ideas about it quickly - sharing somone else's content and making money with it while not having a revenue splitting agreement is a good way to end up sleeping in a cardboard box. Do you know how fucking crazy Disney is? But what do I know..... It's not like I work in the industry..... Not like I've personally sued people over ad rev on sites streaming my films or films I'm affiliated with.
The amount of exposure you're providing for the content creator compared to the $$ you're bringing in is insanely unbalanced.
Hell why not use your platform/ status for good. Start sharing independent films / short films and do a 60/40 split with the creator - I've go a few I'd love the opertunity to make money on. Not even kidding.
Those making the films encourage them to be shared in this fashion hence why they publish them on a site that encourages embedding and sharing of their videos. Everything I've done is completely on the up and up as far as copyright is concerned.
This is the intended behavior for the content and a highly appropriate place to share it.
