Earlier quoted context omitted.
However, if I were to completely close down my Facebook account, I would lose all of the passive information that is sent to me. Or you could just do a quick inventory of which of those groups / are still important to you. And then sign up again using a different device / email address. Along with, of course, a totally fake user name. And (slowly) sign up again for those pages. Which I guess would against FB's terms…
Creating an account with a fake name doesn't help. Facebook will ascertain your real name through a combination of: - knowing who you communicate with - tracking your online behaviour (on and off site) - collecting your name and contact information off your friends devices and accounts Even if you provided a fake name, you still agreed to the TOS, so they can proceed as if you're still bound by the legal implications…
We know they "can", in principle. But will they? That's something different.
Of course, the better solution is to never sign up with a real name in the first place.
