[arin-ppml] Waiting List IPv4 blocks transferred after issuance

With ARIN loudly sharing that they're scrutinizing transfers to a higher degree than ever before, and the DOJ making it clear they will indite IPv4 fraudsters, leasing is the best path forward for criminals (not that it wasn't already before). For this reason I think that the transfer statistics that John shared before can be discounted in this discussion.

In this case I'm talking about bad actors who provide false information to ARIN to get large block sizes, and then turn around and lease them to third parties. My point is that transferring/selling IPv4 blocks is not the only way to make a large amount of money by providing fraudulent information to ARIN. For this reason it does not make sense to use the transfer/block size information that John provided as validity that a /19 or lower somehow leads to less fraud.
