It is a common misunderstanding of Libertarianism that you get to to do whatever you want to do exactly they way you want to do it. In fact, other people also get to to do whatever they want to do to the same extent, and if that includes revealing information that you would prefer to keep private, that's tough.
also, if something's been submitted to my site, there's a good chance it was already public information beforehand. (just like the above 2 example links I gave).
