I don’t live in the US, so my ISP doesn’t really seem to care what I torrent, but the megathread vehemently recommends to always use one. Since VPNs aren’t cheap and I’m on a strict budget (wouldn’t pirate otherwise), is it really that dangerous to torrent without one?
Look, if you want peace of mind use it, but it is also true that you will most likely be fine with it.
I personally use NordVPN, and I have been always torrenting with pretty good speed. I am pretty sure there are cheaper alternatives.
Good luck to You. :-)
