From Second Life Wiki
"God Mode" is the term used to describe the enabling of administrative tools and features in the Second Life Viewer.
Although the features and menus are compiled into the viewer, if an unauthorized user attempts to enable "God Mode" via- - , or the Advanced > Request Admin Powers menu option, a dialog is displayed informing the user that "Request for special powers failed. This request has been logged". The options available to an authorized user can still be viewed via - - or the Advanced > View Admin Options menu option- although "God Mode" appears to be enabled, the server will not act upon any attempts to use them.
What it can do?
- edit land or region info
- kick or freeze avatars,
- claim land or objects to themselves
- Log everyone out of Second Life
"God Mode" also allows parcel restrictions such as "no fly" to be ignored.
What do they use it for?
Linden Lab employees may use "God Mode" for many reasons, including the privacy granted from being invisible to sensors, reclaiming abandoned land and dealing with griefers.
