Tube8Vip wasn't always a tube site.(where sample and complete videos are housed.) It was a viable studio. It was converted to a tube site within the last two years or so probably by the site owners (after a site dump where all the assets go up for auction and webmasters bid on the best site content.)
However, if, by the way, those owners were Mindgeek / Aylo (you can probably forget ever finding it because they will own the domain and once they have the domain it (seems that it) is theirs forever. That's how Mindgeek / Aylo monitors and controls the internet for adult content. Websites that had adult content suddenly disappear with an http 404 page removal error on the home page. Mindgeek / Aylo will also link a defunct website to its Fake Hub Network thus not showing up as well.)
- just like sex.com was converted from a pin to a board site (like Pinterest) to a cam girls website, with gifs and short videos used as a diversion.
- just like xvideos.com now has a paysite: xvideos red
- just like xhamster has faphouse (their paysite)
Gamma Entertainment out of the Netherlands has been acquiring distressed websites and networks for years, i.e. Vivid Entertainment as the prime example and has put Vivid videos on their Adult Time platform. They also acquired Zero Tolerance, Third Degree Films, Diabolic, and How To Kiss A Girl (and renamed it Addicted2Girls)
-- who knows? If Gamma Entertainment buys Tube8Vip, they probably will try to bring them back into the fold as a viable website. They'd probably make it an Adult Time channel.
