With spam email, the recipient has a chance to recover the mail by looking in their spam folder. No such spam folder is provided to the public on social media.

  Note that in the GreetPause case the SPAMmer will not see the rejection errors since they don't look at the response to their hit and run (ie no one gets to see any error, neither sender nor target), and a legitimate sender should never get the error, so even this may be messy by your criteria I think!

    > even this may be messy by your criteria I think! Only if the recipient sent a false response. If the response were misrepresented then I would object to the technique. But it doesn't sound like that's what happens.

      OK, thanks!
