I am wondering if someone has already created a list of netblocks which shift the cost of their customer's abuse to us by sending bounceback spam informing us to use their web forms.
If not, I'm going to create one so that I can add scores for their netblocks. In a recent review I've found that we persistently get more spam from their netblocks, because they are actively avoiding dealing with it. -- Jo Rhett Net Consonance : net philanthropy to improve open source and internet projects.
