I deleted the Facebook app on my phone years ago, when I learned that the app turns itself "ON" again any time it was stopped by me. For that very reason, I also refuse to have the Messenger app on my phone. I've hardly used Facebook since joining Steemit and do not miss it, either, with all the fake-news, political-crap, etc. But, if I want to check in with someone there, I will login on my browser — NOT via their malicious apps — then log out again.
Very smart of you to take those actions to protect yourself @thekittygirl! I'm not really on Facebook too much either. The political crap is really bad lately...
