Personally, those are among the ones I least worry about - maybe I'm naive, but I'd hope they or their upstreams have learned their lessons. The problem is that nobody knows which of the other 25000+ ASes will be the next AS7007. So I guess we have to modify your suggestion somewhat and, in addition to filtering the "known-careless" also filter the "unknown-maybe-careful" class. Oops, that leaves only the "known-careful" class, which includes... my own AS, and then whom? -- Simon.
