Just the fact that it is possible to make a guess, doesn’t mean it is insecure. I put the bar as high as it is to get this information through other means, if not higher. It is certainly blurry enough for the casual observer; it certainly can’t be captcha’d.

For instance, why don’t you search for his name on Google and find one e-mail address. Then add it to Plaxo and see if you don’t get all the information above? Then compare this to my blurring. Which was easier? Now that you know the information, which was more accurate? (I’ll bet that your initial guess of the data on the right is incorrect.)

Does the fact that the answer to both is the latter make my blurring “sufficient”? I believe so. People like you may live in an absolute world in your own isolation, and thus there is only a single right way and many wrong ways. People like me believe “reasonable doubt” doesn’t mean “any doubt”—most statements in the world have some built-in statistical error component and there exists nothing that can reduce Type I error without Type II consequences.

Then again, I don’t wear a tin foil hat.
