It sucks for everyone involved that it went public and such, since it might be embarassing to their families. But otherwise, it's not like this girl did anything all that shocking. She slept with some men, she just happened to write about it. Getting this to the point where it got posted online might be irresponsible, but sleeping with some guys doesn't necessarily make her a slut. Hell, each of those guys in the powerpoint has probably had more partners than her.
I mean, it's shocking, girls like sex? Impossible.
