I Know That Girl is a Mofos network paysite originally launched in 2008 with a premise of featuring unknown amateur women. Over time the site shifted to shooting with established performers, retaining only the casual gonzo aesthetic — POV angles, handheld camera work, and a "homemade sex tape" framing. Membership grants access to the full Mofos network of 45+ sites. New scenes are added roughly once a week under the IKTG banner. Downloads require an additional fee. Navigation is a known issue: accessing IKTG specifically within the Mofos portal requires browsing by the IKTG tag rather than the site dropdown. The original amateur premise no longer holds, which may disappoint users expecting genuinely unknown talent.
