This is not the first (and likely not the last) time a Moderator has acted reflexively. The verbiage 'Needed' in "Subscription Approval Needed" and "Message Approval Needed" notice messages iseems to be misinterpreted as meaning 'required', and that some Moderators believe they must APPROVE, as that is what they are 'supposed to do'. Some may even fear that if they do not approve their email List may cease to function.
It would be better phrased as:
"Subscription Approval Requested" and "Message Approval Requested"
or "Subscription Approval or Rejection Requested" and "Message Approval or Rejection Requested"
or perhaps the more neutral "Subscription Request Received" and "Message Requiring Moderation Received"...
