I never care about organizational customers. Given they generally have
/29 or larger netblocks, they are forewarned concerning ARIN and get to
enjoy long conference calls while we discuss how exactly they'll be
using IP Address space.

This sort of thing makes better sense than asking for residential
customer details; although I'd probably argue against uncensored views
of configs. I don't believe in security through obscurity, but I also
don't believe in letting people view snmp community names and encrypted
passwords if it can be helped.

to generate that information. Depending on the size of the request, you
may be asking for a database report instead of monkeys hand typing. That
can take days to get requested by some companies.
You rarely ask for it so it may be little work to ARIN, but it is a
burden to the requester.

Granted, this makes it more attractive for someone to stay with PA space, but creating hardships for that reason doesn't seem appropriate (dual standard?).

I think there are many things ARIN can do or request that doesn't
include residential customer information or unfiltered access to a
config. Some of them, such as meeting sessions would provide greater
assurances of accurate details and should take less time to verify than
reviewing a report of names (supposing ARIN actually reviews the report
and doesn't just say, "They sent it, it looks okay, so accept it."). It
also falls into the standard ISP/Corporate structure that is allowed for
standard vendor interaction (Some places may let vendors run free, but
some of us watch every little thing they do and restrict what they can see).
