I just don’t care about any of that at all. I have around 100TB of seeding accumulated over the years, no VPN, zero security measures, nothing ever happened at all.

Given that it’s Hetzner, there’s not much you can do besides telling them “oops sorry didn’t know this was illegal” and proceed using a VPN on your seedbox, go private tracker or just use a different hoster. Hetzner isn’t a big fan of torrenting since they have the (german) feds in their neck.
