Don't those have their own problems, though? Like their domain gets blocked, so you have to find it again. They video quality is just kinda ok, and if you want a copy to stream to your TV, it's either not possible, or won't look very good. Years ago my partner used to use some of these sites to watch some foreign-language shows that are just not possible to get in the US at all, and it just always seemed so sketchy and unreliable.

How do these sites fund themselves, anyway? Ads, I guess? Tho not sure what ad networks will show ads on sites that are 100% copyright infringement.
