Quoted from DaWezl:Facebook not only monitors your searching, but it monitors your texts too. I’ve mentioned rare medical conditions in a private text—nothing that I have or would ever be googling—and the very next time I went on FB, the ads were all “How to treat (rare medical condition)!”
I don't have a Facebook account. My wife does. We have our own Windows accounts on the main PC. Shit I search for shows up on her Facebook. Gotta be a violation of privacy there somehow.
