History
Can be overwritten programatically
Event if you have a list with WriteSecurity set to 2, you can still perform edit and save operations that run under SPSecurity.RunWithElevatedPrivileges.

The key here is to make sure your list item has been instantiated from a List not using SPContext.Current.Web but rather clean SPWeb object.

This is because SPContext carries the context of a user before the elevation and hence regular-users security will be applied and save operation aborted.
