Given the sheer volume, I honestly wonder if a human does ever see it unless it's called out on Twitter (or whatever).
Even if it's flagged as an Iconic Image, you have to look at the context and see if it isn't posted by Jared from Subway.
Easier to auto flag than make a "waiting for glacially slow human" queue. (Esp. when one-million-moms has a protest van idling on the launch deck 24/7.)
