Yes, this has been going on for quite some time now.  One day I got six of
these in response to the same message I think.

Maybe someone brave would like to actually respond to this antispam thing
and get a real message through to the user telling them to turn it off or
unsubscribe.

(Or is there some evidence that this is an email harvester or something
deceptive?)
