I agree, more context would be helpful.

In my mind there are two components of this that are in direct tension though, regardless of numbers:

1. Humans having to review ad content is legitimately traumatizing and awful

2. Automated systems can miss obviously harmful content, which should never be allowed

To me this means we probably shouldn't permit these systems to scale as they do, because the company profits from harms to its own workers and/or ad viewers. I worry that we've normalized a business that shouldn't exist in its current form, but it prints so much cash that no one is willing to stop it.
