PerfectGirls.net was registered by some enterprising perv way back in 2000. It’s a sweet enough name to get traffic just by existing, so for a few years it was just ads for different porn sites. A couple years later they started hosting videos, and by 2010 it looked very much like it does now.
Don’t think this means the site is stale. They just figured out a format that worked and stuck with it. There have been refinements over the years, and they continue to improve, but the core look is the same: a huge grid of dirty movies, featuring every type of hot slut engaged in every imaginable form of depravity.
