[anti-abuse-wg] Why SPAM exists in 2017

Hello Everyone,

Famously, during 2004, Bill Gates promised the world that Spam would no
longer exist by 2006.

More than a decade later, spam even penetrates the very best "insert whatever 
name here" technology. 

It is 2017 and apparently society does not understand why spam still exists.

Of course, all of us know why there is still spam. 
//donning flame retardant suit (and tinfoil hat for good measure... )

For those that lurk to learn, or, for anyone with no pov on why there is still spam:

********************************
Spam exists because society does not agree on a single protocol to stop spam. 
(We do not all even agree on the definition of what spam is.)
In society, some filter emails by DNS, some by IP number (worrying about
dropping emails from co-located domains that have not updated their
wordpress and are pumping out 1 legit email for every 1000 spam, etc
etc - we should also discuss this sometime?)
********************************

The concern for "false positives" outrank that of sender reputation and is out of whack.
(and we, society, do not want to change this)

let us take a closer look at a practical (and factual) example of this imbalance:

Fact: Both Google.com and Yahoo.com send out spam (unsolicited bulk
email - where bulk is defined as more than one or two of the same email and 
unsolicited - as simply not requested or expected) 

Fact: We all receive many times more spam from yahoo.com as we do from google.com 
even though google.com transmits many times more ham than yahoo.com
(Another simple truth: We all receive much more criminal activity from yahoo.com 
than from google.com)

If you wish to dispute these simple and factual numbers you can look at
the IP ranges in public data related to abuse, as the statistics report exactly 
the same facts that I am claiming (and experiencing))

Yet, we will be hard pressed to 'drop" incoming from yahoo.com simply
based on sender score, we also do not use other RBL, that lists Google.com 
IP numbers, for drop. (as our users would have hissy fits if they did not get email
from example at yahoo or example at gmail - in fact - they may simply move
their email hosting to google... - because google/yahoo cannot be
wrong, it has to be @example_of_small_isp...

Our user(s) want to receive email from grandma, even though grandma has
just dumped 10000 unsolicited emails asking for donations to send her
old age club to the beach for "insert name of special and/or religious holiday here"

Your thoughts?
