Many don't even know about it until they get a lot of complaints or 
their server crashes because of the bounce handling, or is blocklisted...
and while you can try to educate those who were detected to generate 
backscatter, it's impossible to educate those who will setup new servers 
in the future! The need for a license to administer a mail server should 
be required :)

If they can't configure their system to reject invalid recipients at 
smtp time, there is no hope that they will setup SPF checking correctly!
