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?
I personally wouldn't take the chance. Mullvad is €5 a month, and is worth it to me. My ISP completely shut off my service before ever giving me a notification. I had to completely restart service after going full Karen and blaming it on "my kids." I would do a few searches and find posts or info relevant to your area or ISP.
But barely anyone else provides it too. Proton has it kind of but the amount of servers are restricted so yeah great higher ping/slower speeds depending on where you are from
