I only had half a dozen, all from the last month. This is pretty surprising. I use Instagram regularly, though I only sign into Facebook occasionally.

All of the activity I had was from games that I casually installed and then deleted in the past month. These are games that I signed into with Google Play, which displayed advertisements primarily for Facebook.

Speaking of which, some of Facebook's advertisements are absurd.

"Start Reacting Today".

"This is a summary of the 285 apps and websites that have shared your activity." hmmm, that's more than I expected. A lot of them are from sites which probably had a Facebook pixel on them.

"This is a summary of the 16 apps and websites that have shared your activity."

Not bad!

Only 4 for me, woot!

Delete Facebook. I did so years ago. Get out of their web.
