Disclaimer: I'm bout to have the most schizo take fyi, frankly because its fun.
1. You're right, she shouldn't, but that's not the world we live in. Using an analogy, imagine there's a minefield, signs everywhere warning people not to go in there, in an ideal world, these mines wouldn't be here, but they are. Assuming someone disregards common sense and strolls into the minefield and steps on one, most of the blame is on those who planted said mines, but the person who ignored common sense is also to blame; these things are not mutually exclusive. Social media is a minefield full of freaks, and she time and time again disregards common sense and then keeps none of the blame for herself.
Regardless, I reiterate my point in that it's weird to have sexual images of yourself on the same account as underage pictures; that's like cutting raw meat on the vege board
2. I also think they're freaks for saying that, but I'm also willing to give them the benefit of the doubt. This is where my point before about keeping the sexual and underage pics seperate; if you don't, theres no distinction between them. I doubt she put her age under the posts, so maybe some cracked out gooners made some idiotic and gross comments.
