The proxy settings are the important ones and if the password/username is correct, then you have set it up OK, except you need ltconfig plugin and enabling force-proxy and anonymous-mode setting, so a disconnect doesn't falls back to your own unproxied IP.
Do you have verizon or comcast possibly? These additionally have let the industry install spying tools on there system to find copyright infringements. I'm just guessing here, but i'm thinking they will "get you" just by downloading a torrent meta-file, or just visiting the release sub-page, from a non-https tracker, as they can see the full url there meaning the release name also usually as many trackers have that as last part of the url. Https will encrypt not only page-content, but also last parts of the url, and dns lookup also only shows base host-name and not full url.
Using proxying with a libtorrent-client without force-proxy enabled, will many times be ok provided that the connection was stable throughout, but will let your real IP through if there's a problem with the proxy and the connection breaks at a time.
Note, if using libtorrent older than v1.0, then anonymous-mode is enough, as force-proxy functionality is included there and the option hasen't been splitted in two yet.
Also, you can just use the VPN which is included in your PIA subscription.
Lastly, could you please kindly post the infringement-letter here with your personal details removed, or PM'ing me it? I'm interested in e.g. if they also list your port used in addition to the IP, so if that is the case we know they tracked your through the actual torrent-swarm and not the tracker which I was speculating. Thanks in advance
