I just started to like Just Like Fire...her personality is horrible.
How is anything she's said even remotely horrible? Her private account was hacked, do you expect her to stay silent and just think "oh well"? It's literally an invasion of her privacy and she has a right to defend herself. Be quiet.
A private facebook? Okay, but Twitter and instagram? That's weird as hell.
Maybe it's to share photos/videos of her daughter/family moments with people only she wants to share it with? e.g. Family, friends...? It's not that abnormal.
