So explain how this is superior to DNS entr(y|ies) stating who your peers and upstreams are. And there's nothing to say that one could not specify allowed filters in DNS, too. If someone wants me to advertise 192.168.7/24, and DNS indicates the proper netblock is 192.168.0/19 and their ASN is not origin or adjacent hop, I'll be suspicious. What I do from there becomes a policy question; I probably would contact the IP block owner to verify the request.

Clueless and malicious people never buy from the big ASNs. If said large ASNs don't filter, you still have a problem. If they do, your problem is closer to the edge... the as-path to reach the "real" you will be longer than the imposter at those points.
