Teenhitchhikers is done. It's one of the Reality Gang Network websites. Along with Milf Cruiser, Euro Bride Tryouts, Big Sausage Pizza, and Adult.com. Manwin / Mindgeek purchased the Reality Gang Network in February 2008. They kept the RG domain as part of the licensing agreement. They still own it. If anything, they redirect traffic now to Fake Hub / Fake Taxi, etc.
They next scuttled all of the scenes from the websites because the Reality Gang Network was competing with their latest pride and joy at the time: the Reality Kings Network in gonzo porn. This was all made worse because they never brought the accompanying photo galleries from the sites over as well. How do you do that? Forget to bring the photos over? So yes, Manwin / Mindgeek really fucked up this acquisition.
After the affiliate money dried up (what webmasters use to direct traffic to / from the Reality Gang Network to their websites as part of a sharing arrangement) -- all the websites were purged off the internet except for Big Sausage Pizza. This occurred in late 2009 to mid 2010.
In 2015, Mindgeek put the final nail in the coffin. They took Big Sausage Pizza off the Brazzers PornPortal. The end.
