I'm not sure if that's exactly it. It isn't quite coercion. Facebook's tone and methods of communication often seem more like a manipulative but charming narcissist who is insidiously trying to rearrange your reality. You think you quit the site and suddenly they are back at your front door edging even deeper into your life than before, using every manipulative trick possible. Maybe there needs to be a new term for it.
