I understand you're looking to report on your content administrators for the site. I presume these are moderators? If this is correct, then unfortunately, existing reporting (e.g. CMR) don't filter users by permission levels to cover this use case. If you need to look users up, you might check the Jive Admin Console > Permissions, but otherwise there are no automated reports.
If this is an important feature you'd like to see, I would recommend submitting a feature request idea in the Ideas for Jive place to help capture this for our Products Team.
I hope this helps. Let me know if you had any other questions on this.
