IIRC, Facebook sends those messages only when they've detected an account's usage dropping off. When I was a regular user, I never got them; but when I stopped logging in for days or weeks at at time, they got more intense.

They're a deliberately designed mechanism to keep addicts hooked.

That would match my usage pattern, so I guess you are correct. I'm using Facebook only rarely and am definitely and completely away from it for several days or even weeks between periods of usage.
