I've been aware of how Facebook attaches people to you for a long time, so I deactivated that one, made a new Facebook several years ago primarily for development purposes, different name, different email address, friended a few people from one particular circle, never installed it on my phone

Occasionally I will get random friend suggestions about people in different chapters of my life

Facebook didn't have my address book, or a big enough graph to make these connections

I hadn't considered that those were the people merely searching for my name or variations of it
