Giving away any data is bad, period. I hate this fashion that nowadays every "expert" holding a share is granted access to data, that even the NSA isn't getting that easy. Starting to give away such data to "researchers" is evil, let alone that all that "serious" statistics are just bullshit. No exceptions in regards to privacy! An "exceptions" is a violation of privacy. Why not giving away telephone numbers? Everybody anyway could dial each available number, so it doesn't matter to give away the numbers, right? ;)
