I have several “orphaned” projects in CircleCI that I am unable to purge.
It seems that, if I stop watching a project in CircleCI and then delete it in GitHub - it’s gone in both places. On the other hand, if I delete it in GitHub, forgetting first to stop watching it from CircleCI, I lose control over it and cannot ever get rid of it.
I found no way to deal with this using the REST API either.
I create and drop repos/projects a lot when trying to get a working circle.yml. My workaround has been to create and drop GitHub user accounts.
