I'd like to back this idea!

However, even if ICANN itself suddenly gets stroken by lightning of technical
wisdom and starts announcing unused /8's - that won't prevent offenders from
announcing more specific routes, will it? On the other hand, announcing /24's
will really pollute the global routing table, which is big enough anyway.

Still, having a service like Paul Vixie's AS7777 would help a lot: an ISP
willing to receive blackhole routes would bring a route server on their
backbone, establish a peering session with "IANA blackhole AS" and use the
routes to construct filters etc.
