I am a little amused that it appears we caught my parents spying on our Facebook profiles.
I am estranged from them, haven't spoken to them in years. DH had a profile pop up in his "people you may know" that was named for my old dog. The profile was created last year and the cover photo is a Harley, which my father rides. It's all too much to be coincidental.
Anyway, there are no mutual friends, we don't live anywhere near them etc so there are no "connections" which would cause it to pop up in DHs list. After some googling, turns out that sometimes people pop up there if they are lurking on your profile all the time as FB assumes you must know each other.
Also, now I have blocked them, they'll know that I knew they were spying
