The problem is the for torrenting traffic is still traceable to you specifically.

Where an aggregate VPN that keeps no logs isn’t able to discern who was using what connection at what time.

If your only goal is to prevent your ISP from seeing traffic, sure. Otherwise it’s not “better” solution.

So the general tailscale actually uses peer to peer wiregaurd connections. Headscale is the middle point to negotiate these wiregaurd connections.

So none of the traffic moves through the VPS.

As for a VPS itself, it’s noore unsafe than your local bare metal. It’s still an application publicly exposed and needs basic precautions like fail2ban or crowdsec
