Link: Pollution in 188.8.131.52/8
IANA has recently allocated 184.108.40.206/8 to APNIC, which has caused a certain amount of concern that it is 'polluted' by people already using it for various reasons. Pollution in 1/8 is a report from RIPE Labs on what happened when they announced routing for some bits of it as part of their debogonising work.
This is clearly going to be what they call 'interesting'.
