How much becomes public knowledge about you (me) the moment you (we) use a
freeware bittorrent client to download/upload a shared .torrent?

I'm sure your IP address and your ISP and a rough estimate of your
geolocation from the IP address can be had almost instantly. Certainly what
you are attempting to upload & download is public knowledge, as is your
bittorrent client-but what else do they know about you (me) right off the
bat?

I'm not asking what they can find out if they subphoena your ISP (which is
your name and address and entire upload/download history).

I'm asking what they know from your use of the bittorrent client alone.
a. bittorrent client & version
b. IP address, ISP, and geolocation
c. downloaded/uploaded files
d. ? what else do they instantly know about you ?
