We should also take into account the network abusers and spammers out there. The longer timetable for coming back for another transfer would go toward keeping space cleaner, longer, and letting the spammers stew in their own dirty space.<div>

</div>I would agree, but would also argue that the shorter we make the waiting<br>
period, the more incentive we give for someone who might be inclined to<br>
"game" the system, by acquiring as many addresses as they can justify<br>
prior to exhaustion (causing a "run on the bank") and then turning around<br>
to transfer them again right after exhaustion.<br>
<br>
So, does a 24 month waiting period appropriately balance the legitimate<br>
need for address recipients to become transferors with the need to prevent<br>
"flipping"? Or should that timeframe be shorter/longer? (I know Leo<br>
already answered "I don't know", but perhaps others have some input.)<br>
