Around about 2013 Utorrent client had a group chat feature, I distinctly remember downloading a film near release and within the client fellow torrenters’ where chatting, my then dyslexic ass cant recall the chat but given the date, most likely slurs.
BiglyBT (aka Vuze previously Azureus) has a decentralised chat feature akin to IRC. It’s not very active but it’s technically very interesting and still working. Rooms can be based on per-torrent, language, region, general purpose and even custom.
Oh damn I forgot about Azureus
Sick! I wanna check that out
