That's exactly what Public Suffix List is meant for: to make it possible to distinguish between domains whose subdomains belong to the same organization, company, customer connections to the same ISP etc. and therefore should be treated in common; and domains whose subdomains are publicly available to register and therefore are independent from each other and should NOT be treated in common. The former are not on PSL; the latter are. So if anybody (and especially a large provider like Google) wants to play with "domain reputation" thing, PSL is a must to be taken into account. How else would you distinguish between eg. something.ibm.com and something.co.uk ? :) -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
