Hardcoded password in Confluence app has been leaked on Twitter
> To figure out if a system is vulnerable, Atlassian advised Confluence users to search for accounts with the following information:    User: disabledsystemuser
    Username: disabledsystemuser
    Email: dontdeletethisuser@email.com

Why does this even exist at all? It doesn't even seem like a default admin user. Is this for automated testing and somehow ended up part of the deployed codebase?
