Beepers can also be used to track you down!

true.  I don't return pages from wierd or unknown numbers because of
the rash of pay-service fraud incidents.  (Get a 900-type number in an
area that doesn't use '900' or '976'.  Make your number a $20 or so
charge.  Page lots of people with the number.)

Or you can find out the user->id mapping by bribing/breaking into the
paging company, and look for certain numbers being sent as
page-strings to certain people.
