In this scenario you outline, combined with your proposal of a registry announcing 'black-holing routes' -- what compels the ISP to accept and act upon the routing announcement?

And how does this different situation protect them from the lawsuits you suggest below?

What "compels" ISPs to filter 0.0.0.0/255.255.255.255 from their peers and not to announce it to their peers? I believe Paul Vixie is having a BOF at NANOG to discuss best practices between ISPs. And now that I don't operate a network, I've thought about publishing my full peering agreement as a template.
