This brings up a good point which came to mind recently.

What process(es) do folks use for cases where an address block and/or ASN
seems no longer have whois info associated (eg. where authorization to use
may have been revoked)?
Do the RIRs have a process for notifying the community or at least the
upstream providers that something has changed?

Thanks for insight from the community.
