[tor-relays] Best practices for the hosting provider of Tor exit nodes?

Good afternoon,

As I’m reaching out to hosting providers worldwide to see if hosting Tor exit nodes is within their ToS and AUP, most hosting providers are requesting hardware specifications and bandwidth requirements; however, I would like to point them to a resource showing best practices for the hosting provider, and maybe one that shows expectations of the Tor exit node operator as well – for example SWIP’ing the IP address(es) to the exit node operator – so that the hosting provider knows what the exit node operator expects of them, and what they should expect of the exit node operator.

Does such a resource exist, and if not, what would you request/add in such a resource?

Make your day great,
Isaac Grover
