No, they are not. This is likely a troll posting, as Reddit /r/ is making the idea of women posting selfie nudes seem legit. Don't fall for it. It's a prank, and once, posted, those pics are there forever...
Well honestly? I dont like her but not because the nudes (i really dont know the reason why..maybe just because im jealous ) and i think that nudes are ok if you dont put them in public by yourself..and i tell this as a totally streight woman. And btw. Those nudes for her support is by my opinion idiotic...sorry for my bad english and long comment :)
