Apply the “Account::Dormant Namespace::Successful Namespace Request” macro to the Namespace requesters ticket and mark the ticket as Solved.
Namespace is not available
Apply "Account::Dormant Namespace::Failed Namespace Request" macro and mark ticket as Solved.
Does a login in response to dormant request mean that the account is active? No, the user has to explicitly reply to the dormant request saying "I want to keep my namespace". If the user hasn't responded and has just logged in, send a final message saying something like, "I see you logged in at X, but you need to let us know here if you want to keep your namespace".
What constitutes data in the account? A group, a project, etc. means data. Unless the project or group is empty, or there's been no activity for 2 or more years.
