David, I think that the text is clear:

"within thirty days of their receipt.""

Who has these concerns and what are their basis? My understanding and
experience is that addresses are held for six months for reasons
related to filtering. Bogons are less likely a problem with legacy
addresses, not more. As exhaustion presses on, filtering (routes,
RBL's) will likely become less of an issue. There are going to be much
bigger things to be concerned about as exhaustion presses on.
