I can easily enough press delete or set up filters to prevent your messages. Just like I can open up my junk mail, fill the prepaid response envelope with other received junk mail offers and mail it back to them on their dime. Which sure it is a time waster it provides me with a sense of satisfaction.

As for phones I can add myself to DNC lists, same with my cell. So again maybe a DNS list could be made, or well you could use licensed or purchased opt in mailing lists just like the junk mailers do.
