Robin, once you've set up an account, you do get suggestions of "friends" based on who you've connected with. One way to reduce the risk is to not request or accept a friend, that way there's no connections, dont post anything, dont use your photo, you can also use a different name when setting up. I have a police officer friend who does that. I have very few people on my account, I'm very careful. Just use it to access support groups.
