It's kinda interesting when people started hiding age/gender, then putting in different values, at times I think that alone has accounted for most people here.
Don't take me wrong though, ostensibly that information is nobody else's business, but the ease with which it was taken and spread seems to tell something about people's commitment to biological facts and how fluid they take their virtual identity.
And yes, I eventually decided to hide mine reciprocally because it was just insane I couldn't see other people's info, unless it was fake, but they could see mine.
"Everyone here maintains a fake personality" is different though, but trying not to write a book :p
