I’ve read on reddit I think that if you are torrenting using a private tracker you’re gonna be fine even without VPN. The question is: isn’t the tracker is just a server that leads my torrent client to the pieces of the file on the seeders? And the connection between me and the seeders is p2p, isn’t that type of connection is what makes your ISP snitch you? So what is different about private trackers? And where to find them?
They have the public IP and a timestamp, which lines up with the ISP DHCP logs.
That said, at least for several major carriers in the US, your public IP changes very rarely. Like months or years with the same IP.
