[I'm not sure how a website that on its face seems to perpetuate the culturally normalized obsession with appearance and thus supposed sexual compatibility and success as the highest determinant of evaluating potential and real relationships, provides a service that "turns dating upside down," but]

The idea of mutual trust is dubious at best. What prevents two parties from conspiring in advance so that a third is tricked into believing things that are not true? I will say this: the majority of rapes and sexual assaults are committed by those who are very close to the victim, not by strangers -- and the rapist believes what they are doing is "sex".
