Do nothing in private repos

[JasonEtco]

Because of CI permissions, if the repo is private then the ci-reporter won't be able to access the service's APIs for the builds. There should be a check in the status event handler to prevent acting on a private repo, which would incur errors.

You could ask the user to run travis token --pro and give the app the result.

Yep! But then I'll need to keep track of the tokens, which means I'll likely need a database to store them, and that's more than I want to do right now. I may have to anyway, CircleCI may always need a token, but if I can avoid a database that'd be nice.
