This is actually quite scary. They seem to be technically capable people willing to provide a service to law enforcement. They write on the Russian version of About Us page: [1]
We are ready to share our data, providing automated API to raw data or aggregated reports. We also have technical means to catch users who share torrent downloads. By connecting to user's computer and downloading a small piece of torrent, we can get a TCP-log of communication with the user. Data in this log have a unique "print" - crypto hash, which matches hash from the torrent. This allows to indisputably prove the fact of distribution of content from a given IP address. It will be important in Russia soon. [...] P.S.: We also can build recommendation systems, deanonymize users of torrent sites and many other things.
