Setting your map on MX to "Unreleased" does not mean the map is hidden or inaccessible. Other players can still access your map by using the Status filter in track search, or by visiting your profile.
If you're wanting to properly hide a map/make it private until release.... you must click the "Hide" button at top right on the map page after the map is uploaded. You can of course use it in conjunction with the unreleased feature. Don't forget to unhide the map when you release it!
"Unreleased" is normally to be used for beta maps you want others to test. We'll try to make this more clear in the future on the upload page itself.
