Can I let people get out of my Facebook page?

What do you mean by that do you mean Delete them as a Friend ? if so yes you can go to there Profile then where it says Friends click that then click Unfriend

If this is not what you meant Please update and Explain a little as it may be Unclear as to what your Asking

Up to you, as a compromise post that in a month you are going to have a clean out of followers/friends etc to clean out any stale followers, just paring down to family and current irl contacts etc and if anyone feels they want to re-friend they are welcome to.

I suggest you go talk to Rod Serling about this. "Lost in someone's Facebook pages" sounds like a good Twilight Zone episode.

You can let yourself out of Facebook if you're not interested in friends that you never see in person.
