That is the main reason MAAWG regulars got together to publish that informational RFC

But rfcs, informational or not, are not "enforceable"

I can no more tell SORBS to stop their listing practices (though those have considerably improved after they were acquired two or three years back by a commercial vendor, Proofpoint) than I can, as I pointed out, force some of the people here to stop what they post [I wouldn't do that, ever .. though I would criticize them, like I have criticized poorly run blocklists before]

The point is that a legitimate service might have a user which for a number of reasons (email account hijacked, for example) sends "bad" messages. This happened a few times in our service in our 20+ years of operation. Most  of the blacklisters block first and ask later (if they do take the trouble to ask, which is not true of most of them) even for perfectly identified services (meaning fully identified in WHOIS and for which you can easily reach the admin).
