How are fake profiles adding me on FB when I'm private?

This is like the fifth time in a couple of months. I can't be searched for unless you're a friend of my friends and they aren't friends with my friends.

If you have liked and commented on public pages, people find you on them. It can also depend on your friend's privacy settings. If your friends setting is public, or friends of friends, and you comment or like on their stuff, then others can see what you have done.
