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…

In Organizing multiple Git identitiesRelated: my own project to handle SSH keys for GitHub:

The project might not look active, but that's because it just works. 12 years old now.
In Organizing multiple Git identitiesThe manual encourages bad SSH practices.
The server could collect SSH public keys and use GitHub to resolve them to GitHub users to deanonymize users.
To protect yourself against this kind of problems:
1. Put this block at the end of ~/.ssh/config:
Host *
ForwardAgent no
ForwardX11 no
PermitLocalCommand no
# Avoid keys being propose to any SSH server we connect to (ex: whoami.filippo.io)
PubkeyAuthentication no
IdentitiesOnly yes
AddKeysToAgent no
2. Use a separate private SSH key for each organization you connect to. You must create a config entry to tell OpenSSH to use it. Ex:
Host shhhbb.com
PubkeyAuthentication yes
IdentitiesOnly yes
IdentityFile ~/.ssh/id@shhhbb.com

In Show HN: Shhhbb, an SSH BBSUsers of github-keygen [1] might be affected. Please check the public key recorded in ~/.ssh/known_host_github.
Note that github-keygen stores the ssh-ed25519 key since release 1.306 in June 2022. You can check by yourself:
cat ~/.ssh/known_hosts_github
If you are affected, just run github-keygen again to regenerate your SSH configuration:
curl --silent https://raw.githubusercontent.com/dolmen/github-keygen/release/github-keygen | perl
