Null Routing Spews (Re: SPEWS?)

if SPEWS behavior is abusive towards a network, that network does have a limited recourse: null-route SPEWS.

Looks like at least one person recently has had the same idea: http://www.anti-spews.org Seems like a tough road to hoe. By null routing entire netblocks associated with SPEWS, I'd guess that the folks providing bandwidth, DNS, etc. for SPEWS would be more likely to cave to the pressure long before the SPEWS admins themselves. The thing that comes to mind for me is that null routing might present all kinds of legal issues, but at least those might force SPEWS out of hiding to address them. Who knows? - Drew
