Yeah, according to my router, my IP address hasn't changed in 8 months. But this site has me torrenting a bunch of anime, porn and Russian audiobooks ... while I was sitting on a beach last week in Hawaii.

(And I know I'm not being used as an unwitting seeder).

What's actually happening, it looks like, is it's finding any hits on the same Class C subnet as mine.

This ends up more looking like a precursor for some "I know what you're downloading" bitcoin extortion.
