Well, Instagram CAN be filtered out sort of, you only see post from those you follow, you can be a private account, and you parents can be logged into your account on their device, so they can unfollow, block, follow and mange your account. Facebook, is NOT for kids. I already think facebook is a "kidnapper Head Quarters". All the "location" things. And drama at school happens on there so.
I only have an instagram, google plus(Rarely Used), tumblr(Rarely Used), pintrest, and vine.
