I had a similar thing happen a year or two ago: At some point in the past I shut down my Facebook page, but a year later I created a new minimalistic one so I could stay in touch with my family. I posted a picture of a Vespa scooter I'd been restoring in the garage, and suddenly my suggested friends list started overflowing with guys in Indonesian scooter gangs and young asian ladies in head scarfs. (I friended one guy and we exchange "likes" every once in a while but even google translate doesn't understand 3/4 of what he says.)
