I had the strangest interaction with the Messenger app a few months ago.<p>I was spending time with friends, and I took a few pictures of all of us (didn&#x27;t send them through either FB or Messenger).  A few hours later, messenger popped up a notification telling me something along the lines of &quot;Hey, I see you took pictures today of &lt;friend&gt;. Want to send them to her?&quot;<p>Made me feel incredibly creeped out that FB would take my photos and (presumably upload and) analyze them even when I hadn&#x27;t given them to FB.
