If you need to keep certain people from seeing your posts on Facebook, just put them on your restricted list.
Don't want Mom to see you partying?
Don't want people of the opposite political spectrum shitting all over your celebratory posts about your favorite politicians or legislative breakthroughs?
Sick of the alums from your high school who think everything is cute or a reason to praise the owl gods?
Just restrict them. They will not see your posts unless you tag them.
Happy Days are Here Again.
