I remembered something similar: I used to be signed up at stay friends, which is meant to help reconnect with schoolmates. Signed up to talk to my first girlfriend. Anyway, some guy I didn't know spent a lot of time recommending people he thought I could know ... "Oliver S. thinks you may know guy X, Y, Z" was a regular subject of my emails, nearly every day, until I derigstered. He recommended like a hundred people I might have known, all from one year before or after mine, and I'm interested in none of them... I quit because this was annoying. Anyway ... got figured out, which you is you and which you you are?
