Would this be more effective at both stopping the sources of unallocated addresses; as well as sources that spoof other addresses because the best way to prevent your interface from being shutdown by backbone operators is to be certain you only transmit packets with your source addresses. When customers misconfigure their router, e.g. wrong BGP neighbor or ASN, wrong interface IP address, exceed max prefix limit, etc; don't they lose Internet connectivity until they fix it? A properly configure router should never forward even a single bad packet. If it does, isn't it likely to have configuration problems so why continue to keep misconfigured routers connected? Customers are unlikely to fix problems which don't cause them to lose service.
