@thenexusofprivacy I don’t think any kind of direct message from the creator would be needed. It could just be an extension of the existing follow notifications (or follow requests, if packs are opt-in). I’m always leery of having automated systems commingled with normal human channels of behavior, so an auto-composed post or DM just feels icky to me.
Something else to continue on from my other reply to this conversation that I just thought of: if someone has manual follow request approvals enabled, that should probably be used as a signal that the person doesn’t want to be included in a starter pack.
