Here's how you can figure out if your information was in that file:
From your Facebook profile dashboard click on 'Account' in the upper right hand side of your dashboard. Select 'Privacy Settings,' and then on the next page under 'Basic Directory Information' click on 'View Settings.' You should see a page similar to the image above. If the first listing called "Search for me on Facebook" is set to "Everyone." Then chances are, your name and profile URL are in the torrent file.
