Ghost user who doesn't exist but is in a team

And he says…

How does the account appear in the System Console Users page? Is it active?

No, it doesn’t exist

Is the user able to login/use Mattermost?

User doesn’t exist

Does the user show up in the database?

No

As for the last answer, I rely on MM’s command line tooling to report. I haven’t gone through the table of users in the database directly
