Even in the finish location, if any of the “law” fuckers scourging the open trackers, sends an abuse/dmca to Hetzner, you will have some explaining to do as they will raise it as a ticket and require an explanation as to what happened and what is your course of action to remedy it.

Use vpn that allows port forwarding, or never touch public trackers at all, or both.
