> and Bittorrent

What? No, far from it. Bittorrent is pretty clean regarding illegal material (excluding piracy ofc) - which makes sense, after all you leak you ip address and the torrent that you are downloading to the whole network (if you have DHT enabled) and/or to your tracker, plus your ISP can see what you are sending and receiving (while there is a standard for encrypted transmission in bittorrent I do not think that it is widely used). What do you consider as "CSE" anyway? Would a picture of a girl at the beach be considered a "CSE"? If so you might find such torrents (I wouldn't know), but I think that calling it "CSE" is dishonest.

I'm a detective that works exclusively on online child abuse, I regularly arrest people who have downloaded and/or distributed IIOC over Bittorrent.

The definition of IIOC is provided by the Home Office and split into three categories. Ultimately it is decided by a jury although the categorisation is rarely contested.

By what measure?

Number of files shared

Number of files shared that you know about, which I think is a pretty important distinction. Bit harder to track sharing over Tor, after all. (Which is the point!)

I meant the distinction between majority and worst. What is "worst" in this context? And by what measure?
