I would be willing to bet that the IP netblocks being advertised are
unallocated (or, unused within an allocated block). In the past, before
botnets were so common, spammers would often hijack unused netblocks,
advertise routes to them, flood spam from them, then the routes would
disappear, making it impossible to track the spammers.
