Many people who register their domain through Google, and anonymize it with Enom, had their full name and address exposed for a short period after this year's renewal. ZDnet reports that a flaw effecting 280,000 users lead to their domain being renewed, but not their Enom -- so their legal name and address was listed in the public WHOIS data.
Google's official letter described this as only effecting "a portion" of users. Well, I suppose 94% is technically "a portion".
On the up side, hardly anyone noticed this even during the six days the privacy setting were not in force and effected users got a free year of registration. But that will be small compensation to any user who suffer serious consequences from being exposed.
