With scarcity of IPv4 addresses, organizations are more desperate than ever to receive an allocation. If anything, there's more of a disincentive than ever before for ARIN to spend time on netblock sanitization.
I do think that ARIN should inform the new netblock owner if it was previously owned or not. But if ARIN tried to start cleaning up a netblock before releasing it, there would be no end to it. How could they check against the probably hundreds of thousands private blocklist?
They could implement a process by which they announce to a mailing list of DNSBL providers that a given assignment has been returned to the RIR and that it should be cleansed from all DNSBLs.
