PIA is fine for torrenting. I stopped using them because I use a VPN all the time and I don't trust Kape. Literally trusting an Israeli malware company with your traffic.
Also, their server quality really went down, like I'd be connecting to their american servers but I'd end up with a Euro IP and things would end up appearing in bulgarian or whatever. Plus their servers more and more commonly got blacklisted from stuff.
Yeah I wouldn't trust them with all of my data either. I am curious though, why traffic everything through a VPN?
Everything is SSL encrypted anyway, and if you want to hide what sites you're visiting from someone, all you're doing is shifting that burden from your ISP to your VPN provider. I'm not sure I'd trust a VPN provider more than my ISP.
Unless you're in somewhere like China where you literally have to in order to be able to access most of the internet, I really don't see the need.
