How to prove is authorized?

I know I'm going to regret this, and I'm not debating that this particular
network block was hijacked, but I do have a couple of questions.

Perhaps today, but in the pre-CIDR days it wasn't that hard to get a
"Class B" network (what people would call a /16 today).  Even relatively
small networks needed to get Class B's due to RIP, subnets, etc.  If you
had more than about 64 network devices, you probably needed a Class B.
That was one of the big reasons for CIDR.

If you look closely at many of the early registration records for
old networks you'll find lots of questionable entries.

Why was the network for F.ROOT-SERVERS.NET ( registered
in 1984, but the domain for ISC.ORG not registered until 1994? Why does
the city and state for the ISC.ORG domain registration show up as "null?"

Internet Software Consortium (ISC2-DOM)
   950 Charter Street

   Domain Name: ISC.ORG

According to the California Secretary of State web portal, the Internet
Software Consortium filed their corporate papers on December 17, 1997.

So we have a 1997 corporation with a 1994 domain name using a 1984
network.  Is this proof of evil intent?  Should all ISPs immediately cease
routing the network block for F.ROOT-SERVERS.NET because of questionable
registration records?

Back to the original question Chris Morrow asked a long time ago.  What
should be considered acceptable proof?

If Paul Vixie showed up on my doorstep tomorrow, and asked me to route; what proof should I accept from him (or anyone) to demostrate
beyond a reasonable doubt he has the authority to route a particular
