Thumbs up for Blur/Do Not Track Me/Abine "Masked Emails" They work fine for me on places I don't want my "real" email address posted. But, I have to say, given the ubiquity of sites I "trust" asking for my real email address and mobile phone number and to which I've given said never changed info (since at least about the mid-1990s), I might as well be giving the my social sec #. With just those two data points, they can track me from site to site to site to site to site... Indeed, the Apple, the Google Machine, the Amazon, even this frequent flier chat board thingy I visit all the time, all have them both and thus the I might as well be on a billboard saying "this is my ID" now... associate everything with me (understanding that those first three maybe don't talk to each other as much, antitrust and all...).
