Most of you are familiar with iknowwhatyoudownload, the site in which by knowing someone's IP address you can see what were they downloading. Unfortunately it only shows torrents which were added to its database.

I have a peer with static IP address, is there any tools to extract what he/she was downloading?

I wanna do it for good purposes, the peer has very valuable files I want to help being seeded, but unfortunately it is the original creator which decided to delete some of them, because their size is too big (200gb+), I want to track his activity, so maybe he could leave a comment in a tracker where I could contact him.
