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.
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.
