Hey,
I'm the owner of the rentmen account. I'd like to address a few points.
First, it's common for people to misrepresent their age online, including myself. My clients do it, so why shouldn't I? If I've managed to maintain a youthful appearance through healthy living, why should I be penalized in an ageist society? Age shouldn't define someone physically, mentally, or sexually.
Second, it's natural for people to use their best photos when promoting themselves online.
Third, instead of criticizing someone, why not suggest that users set up a video chat with the advertiser to verify their identity and appearance?
