A few of my friends on Facebook (not to be confused with Facebook Friends) who used pseudonyms have been forced to use real names, due to complaints from other users (specifically, politically motivated pages).
With my motorsports photography and chainmailing/jewellery sidelines I specifically use Facebook to somewhat increase my profile though I don't promiscuously 'friend' people, nor do I leave my security settings wide open.
That's likely the kind of stuff I stay away from, precisely because I wish to simply use FB to communicate with my actual friends. I don't like video links or pictures of memes, or ranty articles about injustices or what have you on FB. I also refuse to install FB Messenger.
I am most likely not the target demographic of FB because I use it wrong.
I'm on LinkedIn with my real name, but I don't login or look at it very often. Since that has people I work with, too much activity on there, and my bosses would see when I'm using it and not working.
