No, it’s not. Friend of mine was doing it on regular basis and only stopped because he got Amazon Prime subscription and didn’t need to anymore.

Wait people are illegal streaming twitch?

I guess that makes sense but I never thought about that.

Prime includes Amazon Video or whatever

There were attempts at legal bullying, but mostly with aim to humiliate the victim as the correspondence contains the full titles of porn videos.

the problem is people don't know about torrents, and many streaming sites are based on torrents, so they re-upload the stream while you're watching, which gets you into trouble

how does that work?

For example this: https://en.wikipedia.org/wiki/Popcorn_Time

This was the first one I think, right now there are e.g. Kodi Plug-ins and other media servers that work the same way
