How does this firm (or whatever it is) know I torrented something? My VPN app took a shit in the middle of a download and I think it exposed my IP to some "anti-piracy" bullshit firm that contacted my ISP. ISP emailed to let me know and to "not do it again". How does this firm know about torrenting? Do they like watch these sites and hope someone's VPN slips like mine did today?
Most VPNs can leak some data occasionally, especially on startup. Maybe it changed servers and was down for a split-second, maybe it was just a shitty option to begin with. Maybe the VPN company sold you out. Who knows.
