First, in this thread we are not talking about folks who have not paid
ARIN their dues, we are talking about folks who "sell" addresses
despite not being authorized to do so by ARIN - aka abuse/fraud.

Either way, if ARIN finds strong enough reason to revoke numbers from
Org A who is ISP X' customer, ARIN will eventually reassign those
numbers. When ISP Y calls ISP X and says "hey, your customer Org A is
advertising my customer Org B's address space." ISP X will check
WHOIS, see that they are telling the truth and filter that block from
Org A. If ISP X does not, they will likely see peering and transit
options shrink rapidly.

So in short - yes, really.
