Before looking at VPNs, you should be encrypting your torrent traffic in the client
Note:* Remember that the encryption torrent option only encrypts your inbound and outbound torrent traffic. Although it will not be readable, your traffic can still be intercepted and tagged as torrent traffic. If you want to increase your privacy, you’ll need to encrypt the entire layer 3 traffic (at the IP level), so it is recommended to set Deluge with VPN. To hide traffic at layer 7 (application layer), use a torrent Proxy. And finally, to hide, encrypt, and speed up your torrents, use a Seedbox.*
You also need to fully encrypt the traffic in your bit torrent client. You will get fewer peers, but it’s much safer
