They're affiliated with (or possibly owned by the same people behind) 52longhair.

52longhair sells hairplay/haircut photosets and videos for the hair sold by longhair88.

52longhair also used to sell hairjob videos, ranging from the site owner giving hairjobs to women without their knowledge to actual consensual hairjob porn. All the hairjob videos are now apparently gone from the website.

I think there was something in the news about some of the women (the non-consensual sex ones) making sexual harassment complaints to Chinese authorities, and that the site owner (or one of his associates) doing jail time.
