There are some very cheap VPNs out there. Get a year long deal on Slickdeals, or a similar site. Come renewal time , switch providers and got another discounted subscription for the following year. VPN providers fall all over themselves trying to lure you away from your current provider.
Or, even better, get a seedbox. Many of those even offer VPNs at no additional cost. So you get the insulation of never torrenting on your home connection, and a “free” VPN, that isn’t shared with a million other people, for things like watching foreign streaming services or just plain increased privacy.
Seedbox providers are taking on the majority of the risk by providing the service. It’s in their interest to keep quiet about it. If they’re served with a legal request, they’ll honor it, if it conforms to their local laws. But so will your ISP, who has no incentive to protect your information.
Also, just my opinion, but I think seedbox operators tend to be people who are doing the same things their customers are.
