I don't get why people call this 'Streaming'...
The streaming is when we send over internet the signal, it could be a game, it could be our webcam, or it could be anything else, As example we can see sites like twitch. There we will find tons of real streamers doing their thing. The sites you are sharing in this thread are site to watch movies. I don't think stream is the right way to call them.
Yes these sites are just places where you can watch videos, movies, series, etc.
even though there could be made an argument that torrenting is streaming as you are also redistributing the media at the same time.
Ultimately I think this thread shouldn't be named streaming but rather something along the lines of "Free movie sites" or something similar.
