+=head1 BUG DESCRIPTION
+
+When Thread assets are copied, a new subscription group gets created for them,
+but not by calling $thread->createSubscriptionGroup. Instead, a "blank" group
+is created, and then the users from the old group are added to it -- which by
+default has Admins subscribed in it. So, every time we copy a thread, our
+admins start getting spammed with subscription updates.
