Ad optimizer Rubicon announced acquired OthersOnline, which is “an “affinity scoring” service that determines how strongly a person is interested in particular brands, products or topics.” Business Week frames this as part of an inevitable consolidation of sources of behavioral targeting data. It sounds like a good occasion to dig into their privacy practices.
OthersOnline doesn’t link to any privacy statement from their homepage, but with some searching you can find a blog post about privacy from February 2007. It includes assurances that personal information is never shared, but no mention of whether or how anonymous information or profiles may be shared, whether sensitive information is collected or what policies apply to deletion, assuming those concepts apply to how their service operates.
UPDATE: Since this post, Rubicon has shored up its disclosures. See my post here.
