How is this a privacy threat? All the information in the torrent is totally public, and existed for everyone to see on the internet before this .torrent file was created. Google's cache certainly has copies of all the data too.
What does running for office have to do with this? If you put some sort of compromising information on to the internet, that was probably a bad idea. If that's the case, then you have nobody to blame for your failed political career but yourself. But this .torrent file is just another copy of that information...there are probably another 10-20 other, unique copies out there.
Edit: also, it's not like this torrent makes any of the data easier to access...it's actually probably much easier to just go to someone's facebook page and look at it than it is to download multiple gigabytes of data, most of which will be useless.
Running for a political office in the next 20 years? Do you know the state of your Facebook profile when this archive was created?
