I'm not sure you can pin this all on the advertisers. My interests, according to Facebook, include: - "product (business"), - "Price", - "Providences and Territories of Canada", - "Livestock", "experiment", - "Lizard" and "Shark" (as a hobbies!), - "USB". As far as I know, I neither own nor operate a battery-powered reptile farm. Honestly, reptiles kinda creep me out. They do get a few things correct, but none of these seem "inferred"--it's mostly organizations that I've explicitly liked and...substrings of their names.
