While the analytic reporting in mission control is very helpful, I'd like to be able to exclude personal spaces from those graphs. It really clouds the data, especially since we're an organization with thousands of users and therefore thousands of personal spaces, but only a few dozen communal ones. For example, of the pages with deactivated owners, I estimate at least 25% of those are actually in personal spaces of deactivated accounts, which isn't relevant to our cleanup efforts.
