i’ve never been all that convinced that using torrents over tor was much more than a boogeyman. the pirate based site trackers all use udp. it’s not an easily recognizable workaround to get them functional. plus, most of the pirates i’ve been in contact with absolutely loathe the download speeds they get over tor if they can figure it out. the majority i’ve known have all gone the rather comical “paid vpn” route for protection. for the more patient that use tor for piracy, they’ve gotten a seedbox and cron jobbed dumps from the seedbox over tor.
it’s been pretty rare when i’ve needed to do a workaround to download a torrent due to udp. but, i’m not going for movies or wares. the trackers that host operating systems or other less legally problematic files don’t seem to care about accepting tcp. it appears to be mainly the multitude of piracy sites that blast people with ads that went udp only due to the traffic volume and their crappy business model.
particularly for perfectly legal and larger downloads, i’ve never subscribed to the notion that using torrents over tor is wrong, with the caveat that one does not seed. it can transform a download that would have taken an hour over tor into 10-15 minutes. i absolutely get it when it comes to movie/software pirates though.
