For most users, the need is to stop the spam without blocking legitimate

Collateral damage is an issue.

Collateral damage is the OBJECTIVE.  It is the only thing
that gains the attention of the abuse-enablers.   This is proven
beyond doubt. 

Another issue is the fact that blocking 
is not communicated to the sender in many cases but the messages are 
swallowed silently.

That is an RFC violation.

As for community-based systems, rule of the mob is not always good.

No 'mob' is involved, but users who do not agree to have their
systems polluted.  Procedures are clear and public in the document I
drafted.


I am not saying this approach is bad, rather it has issues that must be 
worked out. If all of these issues are taken into account, such system 
may very well do a lot of good.

For example, if there are standards for communications among ISPs and 
networks for both blocking and abuse reporting, 

There is ia standard; it is in the RFC pertaining to mandatory role
accounts.
