Or maybe it means that ARIN has priorities and recovering
this space is low on the priority list. Anyway, you are
wrong. ARIN does have a way of figuring out that the space
is no longer in use. When some sucker buys the addresses and
tries to use them, they will find out that they must first
update ARIN's records. And when they do that, ARIN will learn
about the deal. At that point, they have to justify their address
space just like anyone else, and only get to keep the amount
of address space which they can justify.

The fact that there are few suckers around to buy these addresses
means that these block have been kicking around for a long time.
But if there is ever a crunch for IPv4 address space, you can bet
that ARIN members will empower ARIN to act unilaterally and take
back the space.

You haven't read through ARIN's policies yet, have you?
