AS Numbers unused/sitting for long periods of time
Inaccurate whois data from ARIN is not a good way to tell anything as
ARIN is terrible to deal with when you need to update an address or
phone number or anything. I know personally as I had to fight for years
to update the data on an ASN that ARIN was billing me to manage the data
