Yes… Being a former PureVPN customer, I can shed some light on this. Only PureVPN's servers in Brunei, Germany, Luxembourg, Netherlands, Romania, Russia, Sweden, and Turkey are permitted for P2P traffic... Just a heads up.
Beyond that though, PureVPN by default does not do port mapping or port forwarding. This is a separate service that you must purchase from them to be able to have the correct ports forward through to your computer through the VPN. Without these ports forwarded correctly, you enlist in the tracker as a passive node, which bumps you to the bottom of the peer priority for some reason I do not quite fully understand. The result is that you will experience little to no upload traffic until the correct ports are forwarded and get through to your computer as a direct connection from the outside world through the VPN.
