[governance] brazil's anti-spam campaign results

[Suresh Ramasubramanian]

Thanks for sharing, Carlos

Cgi.br deserves the highest praise for what they have accomplished.  Now the next challenge in brazil is the huge number of local email marketers who generally don't follow best practice and send extremely high volumes of spam.  Reaching out to them and influencing change in their marketing practices is the next, and far bigger challenge.
