From the article:

While I understand that in the face of IPv4 exhaustion long quarantine
periods are probably no longer a good idea, I think 6 weeks is
shockingly short.  I also think to blanket apply the quarantine is
a little short sighted, there are cases that need a longer cooling
off period, and this may be one of them.

I think the RIPE membership, and indeed the policy making bodies
of all RIR's should look at their re-allocation policies with this
case in mind and see if a corner case like this doesn't present a
surprising result.
