VPN providers often advertise their products as a method of surfing the web anonymously, claiming they never store logs of user activity, but a recent criminal case shows that at least some, do store user activity logs. (...) The suspect used ProtonMail, VPN clients, and Tor to hide his identity. (...) The FBI managed to obtain logs from two VPN providers - PureVPN and WANSecurity. (...) PureVPN was later able to link the stalking activity with Lin's home and work IPs. The information in the affidavit may shock some PureVPN customers, as the company boldly advertises on its privacy policy page that it does not keep any logs.
