Here's one trick.
I use Fluff Busting Purity (FB Purity). They can't save Face Book Purity, so....
Free program, constantly updated as Zook and his morons change the FB program.
You can kill pokes, chats, ALL ads, period, as in full stop.
Whole page of things to select or unselect.
DO NOT fall into their social trap and give where you live. None of their business.
Click the part that says nobody can tag you in one of their photos without your approval.
I have a whole CSS set I can send you. Stops all the extraneous BS and stuff like poker, casino....you can stop all games requests.
Usable for family and friends.
You can select things you put up to be viewed only by friends, or friends of friends....and maybe not the whole nosy world.
It's a royal PITA. Zook seems to be trying his best to rival google in privacy elimination, and I for one won't have anything to do with that part of it.
