I recommend 'ssh -o PubkeyAuthentication=no superlogical.jobs` if you have a public key and want to stay anonymous (beyond revealing your IP).

Why? Because if you use SSH to connect to connect to GitHub, your SSH public key is published at https://github.com/<username>.keys so an SSH server to which you connect could do a reverse lookup.

This is the reason why my ~/.ssh/config has those 2 lines at the end:

    Host *
    PubkeyAuthentication no
