I've shared this before on HN, but it never fails to make me laugh when I think about it: >Several years ago a conversation about a similar topic prompted me to look at the ad targeting data Facebook had on me. At the time I'd had a Facebook account for 12 years with lots of posts, group memberships and ~500 friends. Their cutting edge data collection and complex ad targeting algorithms had identified my "Hobbies and activities" as: "Mosquito", "Hobby", "Leaf" and "Species": https://imgur.com/nWCWn63 https://imgur.com/nWCWn63.
