If you click on any video on the main page it has a huge HPA with linking code to the program.
Click the video it matches that site.
Knowing the size of the traffic xnxx owns and controls I feel it's safe to say this site is fully legal, and has the blessing of the sponsors.
This is someone thinking outside of the box and making a site based on all the ones that steal, but is most likely doing it with the support of the sponsors.
I feel it's safe to say this site is done without stealing any content.
