Remember that torrent yesterday that contained the personal information of 100 million scraped Facebook profiles? I thought it was strange that the guy didn't sell this information, since many companies would be interested. Turns out they are interested.
Reader Clint discovered that all you had to do is use something like Peer Block, which grabs the IPs of the other users also downloading the torrent and identifies which company or university or organisation they belong to. You can check this yourself by hopping on the torrent and doing the same thing.
Here are the major companies that are downloading the torrent. A couple caveats to these. Just because a company is on the list, doesn't mean that it's a sanctioned download by the company itself to grab the user information for some purpose. It could easily just be some dude at the company who wanted to download the torrent himself to check it out. Also, the IP addresses assigned to a company might fluctuate (they usually don't, much, unless major companies change their connection to the internet, so it should be mostly accurate).
