It was someone from the agency gone rogue. Nice guy actually, we chatted a bit and I got some insight as to how things work. He also sent some screenshots showing how they nickname followers to have the information handy:
They work 8 hour shifts, so three people managing pages around the clock. He said they switch between four profiles at a time and just go through the vault for pre-recorded content that the creator submits.
Unfortunately I fell asleep before I could get much more from him.
