I had an account a couple of years ago and then my family found out about it so I started to get messages from relatives I wouldn't recognise in the street if I fell over them.
Googling the question, I closed the account but still wanted to access it to view some aviation related stuff (sorry to introduce aviation on a PPRuNe forum).
I set up an e-mail account in a false name from a library PC and then a FB account in that name. No-one knows what my FB name is, so I browse and view to my hearts content while remaining totally anonymous as I don't contribute anything or place messages on it. Win/win.
