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?
Firms that sue you because you download copyrighted material don‘t sue you because they sniff your internet traffic contents, but because you appear on the tracker peer list. Ony public trackers this is easily visible, on private trackers it‘s not since you need access to the tracker in the first place.
