Given that so many photos correspond to famous singers, models, actresses etc, I wouldn't rule it out that that are not in fact the real thing.
Don't get me wrong, there is some infinitesimally small chance that a KPop singer decided to pop over to Kowloon Tong or SSP to sate her carnal desires for a few schmekels.. But mostly I'm guessing they figure if a guy is horny enough, he'll take what's presented 9/10 times
