You simply purge information that's not kept fresh from the database. It
doesn't really matter whether this "opt-out" takes a couple of weeks, or
a couple of weeks, to take effect. Consider how many Windows Phone users
come by your ranch per month to opt you out of Microsoft's database, and
whether Microsoft should have kept your access point in the database in
the first place, considering it's rather personally identifiying with no
other access points nearby. Everything about your "constantly report on
those who try to opt-out" model is wrong.
