Sonarcloud showing unknown members

So, I went to add a user to our sonar cloud, and while searching for users, I noticed I could see/assign a list of users I do not recognize. Is this supposed to happen? Should this be limited to your organization?

What happens If I accidentally select a user not in my organization?

None of the people listed in that screenshot is a member of our organization.

Well… they aren’t a member of your organization until you’ve added them to your organization. So it wouldn’t be possible to limit to your organization. GitHub, for example, behaves the same way.
