If Vipbox is stealing, I don't know how they do it. The content owners could easily shut them down. Vipbox has been around awhile. Their streams are low-rez so I assumed that the content owners gave it a pass.
They don't stream anything themselves but link to sites that illegally do.
I imagine there are attempts to shut them down, as is the case with other sites that illegally stream. On the other hand, such sites are so prevalent, I'm not sure it would do much good. Shut one down & watch three take its place. Plus, Vipbox is overseas, making such shut down efforts much more difficult.
