Hi IPfail,
"IPfail (Tor Admin)":
The one I received seemed very reasonable in language and scope, and came with contact information for someone with a title that implied that they work specifically on "cyber crimes". I am currently anticipating that this will be a non-event.
Either way, I wanted to share this event with the relay community since one of the questions that I had when first starting out was how much "administrative overhead" could be expected as a result of operating relays.
Thank you for reporting this to the mailing list.
In case there is a resolution that you can publicly share it may be useful for current or upcoming relay operators/servers in US.
Cheers, ~Vasilis
