I have another theory:  The message isn't being re-sent from his hub at all,
its just being reimported into Mystic by Mystic.

When I re-enabled SEEN-BY dupe checking a few weeks ago I may have accidentally
disabled the address checking for point systems that prevents the message from
tossing back to itself.  The latest version (dated 5/17) should not have that
problem.
