9.  A and B ignore ARIN's email and continue to announce what they've been 
announcing.

10.  ARIN attempts to allocate the /20 to someone else, who is not amused.

Note that at this point ARIN presumably has no more v4 space left, so a 
threat never to allocate more space to A or B isn't very scary.  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.
