What does "Admin Approved" mean?

Hey all,

I saw some of these "admin-approved" labels on some people's activity, and was wondering what they meant. After looking at it, it just appears to be a blank admin edit to a guide or device. Could someone clarify what they mean and do? I'm a bit new to this and am looking to learn more about the different editing labels and patrolling process.

Thanks,
