Recently Matt Cutts mentioned he attended Blog Conference for lawyers (don't bail yet it's worth the wait). However John Andrews did a nice bit of cyber-sluething and found something Matt didn't say about a database of online service providers discussed at that same conference
Now Matt didn’t identify it as such… that’s what you need me for :-) Matt simply commented on how Kurt Opsahl of the Electronic Frontier Foundation polled the table about DMCA takedown notices, and pointed out how easy it was to register as an Online Service Provider. But if I were Matt, and that was news to me, I would take a look at that US Copyright web site and when I saw page after page of webmasters listing all of their “other domains” I would say aaaahhhhh…. and fire off an email to a junior Googler to “organize this information”.
Warner Bros Entertainment for example listed entertaindom.com and conspiracytheory.com, which have WHois records assigned to Warner Entertainment, but they also included orgymusic.com on the same registration form, which has a Whois registrant of Astro America, LLC in San Francisco. Nice find for Google, as this allows Google to associate orgymusic.com with Warner Brothers when, based on Whois alone, that was not obvious public knowledge.
