Given its limited practical leverage, ARIN is only effective insofar as its members and customers agree that playing by ARIN's rules is more beneficial than ignoring them.

Thank you John for saying this...  As noted, ARIN's just trying to administer
the policies that the community has developed.  This means that we will revoke
the address space for cases of fraud, and will reissue to one of you to use.

Now, if that's not the desired outcome, the policies are subject to change 
via the public policy process. As it is, folks need to expect that they may
receive address space that was revoked as a result of such misuse, or change
the policies to have ARIN do something else.
