If both networks point default at a transit provider, traffic exchange 
can still work...but as Job said, they will (by default) ignore each 
other's routes regardless of how many AS-hops separate them.

If ARIN has a large pool of ASNs which it believes ARIN is responsible 
for, and are not being paid for, i.e. ASN squatters, then WTH are these 
ASN's not published in whois as Unused/Reserved/Reclaimed/whatever 
term/language ARIN comes up with that clearly identifies the ASN as not 
belonging to whoever might be trying to use it?  That just might help 
deter transit providers from allowing customers to use them.  An automated 
periodic email to peeringdb/whois contacts for the immediate upstream ASNs 
would at least notify/remind networks that they're providing transit to an 
org squatting on an ASN.
