Using unallocated address space

Any time a network is caught announcing non-allocated address space, the registry should bill them accordingly. If they refuse to pay, the registry should yank their ASN. That would be strong encouragement to do the right thing.

Other than making it difficult for people to figure out WHOIS using that ASN, "yanking" an ASN's registration has little practical effect. You can use an un-allocated ASN almost as easily as using an un-allocated address block.
