So this is is really the question I had, and this is why I was wanting to start a dialog here, hoping that it wasn't out of line for the list. I don't know of a way to let a bunch of operators know that they should remove something without using something like this mailing list. Blacklists are supposed to fill this role so that one operator doesn't have to try and contact thousands of other operators individually, he/she just has to appeal to the blacklist and once delisted all should be well in short order.
In cases where companies have their own internal lists, or only update them a couple of times a year from the major lists, I don't know of another way to notify everyone.
I get why people are more cautious and filter entire blocks when just a few hosts are attacking/spamming them, and everyone has a choice on how they want to handle these situations. As an ISP, I want to do as little filtering as possible. I want all of my customers to have access to everything possible. If a netblock changes hands, I want to give the new owner the benefit of the doubt and only filter traffic if it repeats the same old behaviour. We're all using this finite space and I don't want to let the hostile minority slowly ruin what's left of the ipv4 assignments.

How do all the AS's that have their own internal blacklists find out that they should fix their old listings?
