My friend in Italy just asked me how to "share" files over this TCP based protocol, what sites do you guys use and precautions they need to use like condoms with a bully's mum.
Edit: I think everyone misunderstood what I was trying to say, I said "share" because I meant torrenting ;)

Less risk of computer viruses, higher risk of bird flu though.
You could use
python -m http.server
This would create a server with the directory listing.
Give him your IP address and he can download from it.
for torrenting, you only really need a VPN and a torrent client, as for precaution, I guess just bind qbittorrent with VPN. and for sites to find torrents, there's plenty on the megathread or fmhy, tell him to use an adblocker like uBlock Origin
The VPN is not that important here, no one cares about piracy in Italy unless you're streaming football/soccer
