I have often wondered that myself, if they knew that their pages are public. With my utmost respect for them, I have never harassed them. Both Eli and John are on FB too and their pages are uber private, and so is Jordan's. From what I read about it, they are all on FB! This U2 Brazil fan page has breached a high privacy clause, because I keep seeing private family photos being posted EVERYWHERE! That's NOT NICE PEOPLE!!!
I'm going to take a big guess in here that the Hewson clan, aside from almost famous Eve, are pretty no-nonsense and clear about their privacy, kept their FB and Instagrams private for awhile. And despite Eve having a pretty known *REAL* Facebook, and an even more public Twitter with an even MORE public Instagram, which she has shut down alltogether due to all the monstrocity of invasion of privacy that people put on them.
I am pretty sure that these kids are normal, like you and me, and don't think twice about their pictures and the sancity of their privacy. They don't wake up and look at themselves each day and say, "Oh wow, I'm The Edge's kid!"
Shit they might not even CARE that you check out their pictures and pages out of curiosity!
Just please have some common decency and don't share their pictures!
