Would like to start my reply by saying that I received my first spam in
1987, from CompuServ and that imnsho email will never die, it is too
well suited to human nature.

These days, I am trying all sorts of new ways of trapping new spam bots
and figuring out how to get more spam, more data, more bots.
Huge multi nationals like Google etc do not share their data

To understand the small spam problem in 2016, one has to 
understand the differences in modern email.

Mass email providers like @gmail.com @yahoo.com @hotmail.com are
hard/difficult to block - and they know that - so some of them, like
yahoo.com for example, does not spend as much money as say google.com
does - to fight abuse.

If @dinamis.com would dare to send spam - @dinamis.com would simply end
up in a rbl 

Our rbl's commonly block at least 100 yahoo servers for each single
google.com server and the blocks last anything from an hour to weeks,
depending if they stop their spam

Interestingly, if Google is blocked for spam they bounce back to their
user with : technical error at the receiver - this is kinda evil as it
implies that their is a problem at the receiving server, when Google
full well knows that their is an admin restriction due to Google being
abusive...

branding I guess, users have to be kept as mushrooms for as long as
possible so that the large guys can dominate and take over the world :)
