Koos 🆗 is a user on octodon.social. You can follow them or interact with them if you have an account anywhere in the fediverse.
If you don't, you can sign up here.
is there a downside to not being on the main mastodon server?
@bondcliff you can follow people on all (federated?) instances. Don't know how to find them without getting accounts there first though.
