If you’re US based https://en.m.wikipedia.org/wiki/National_security_letterMy ISP is good and have repeatedly fought in court to not give out user information and to protect privacy. When police or anyone else wants information out of them they get a standard form with two alternatives to state why they want it. Paraphrasing, one says "Is this some petty bullshit about file sharing, stupid posts on the internet or other crap?" and the other one is "Is this about serious crime like child pornography, terrorism, murder or anything that carries with it a prison sentence of two years or more?"
If the first box is checked it goes into the trash.
They're cheap as well(100mbit, ~$32 a month, no caps) and they're rolling out 10gbit for crazy people and that only costs ~$50 a month.
(checked out their website to confirm that and saw that 250/250 cost $4 more per month than a hundred, so I upgraded and got a new router)
I mean cool they respond that way to file sharing notices mine does too. Didn’t want to test that and went with a VPN that allows p2p sharing. Regardless the alphabet agencies slurp up that info.
