Facebook is indispensable for me because of groups. A group for my running club, a group for my cycling club, other local groups. All activities are coordinate using FB & Messenger. However I also have a zero friend policy on Facebook. Having zero friends, plus the "only friends of friends can send me a friend request" setting, means nobody can send a friend request. I suggest you try it, it's glorious.
