Well my ISP gives out a dynamic IP address each time my DSL modem connects to them, so this tactic only reveals who downloaded what when they were assigned my current IP. Nothing much can be inferred from this data unless you are the ISP or govt and can tie the IP to the subscriber. And yes, it shows my IP downloaded the movie Zombieland, which I never did, so it is some other subscriber of the same ISP.
However, what does impress me is that somebody downloaded multiple movies and games a day, with books and tailoring instructions thrown in. Dunno if the site counts seeding torrents too, but if not—someone is very busy just consuming all that.
