It seems like there are lots of folks that use it for direct downstream customer-facing allocations and are not even utilizing them for dual-stack services as intended.

Hi Tim, If you know it's 4.10 space (not address space allocated under a different policy section) and you know they're using it for plain IPv4 or generic dual stack, please file a report at https://account.arin.net/public/fraud ARIN takes fraud seriously but they don't have eyes everywhere.
