Do most people look at their Facebook friends' listed family?

[Joe]

I'm asking this because I have two family members as Facebook friends that have extremely inappropriate content on their profiles that I don't want my friends to see. One of them, a girl, has very shocking sexual photos of herself throughout her albums, many of them naked or near-naked, with obscene words in the captions. Her cover photo if you click on her profile is of her dressed up in a near-nude outfit but with little girl pigtails and and the caption says something like "sexy little girl." Another cousin of mine, a guy, has a picture of himself and his girlfriend standing in front of a flag that has a swastika on it. I am worried that my other Facebook friends will see these people listed in my family section and click on their profiles out of curiosity since they're related to me, and be shocked at what they see. Besides just my school friends, I also have teachers, neighbors, adult friends of my parents as FB friends, and I would be humiliated if they saw this. My track coach even has a 10 year-old son that is friends with me, and if his young kid saw any of this crap he would be pissed at me. What I'm wondering is do most people click on their FB friends' listed family out of curiosity and look at their profiles, or is this not something I should worry about? Thanks
