Do not visit this site. If you visit it once and then visit it after a while they will fill it with crap that you did not download in order to blackmail you or something I presume. Alternatively they might start tracking you only once you visit it. Even if they are honest it is extremely inaccurate (it had 8.8.8.8 torrenting anime a while ago for example)
Bogus results can simply be the result of ISP IP address recycling which, in my case, is pretty obvious. Besides, why would they wait on an IP address visit to fill it with blackmail material? The suspicion doesn't make much sense to me.
