Share of followers flagged inauthentic by tier:
— Nano: 4–9%
— Micro: 8–16%
— Mid: 14–27%
— Macro: 18–34%

If a macro account carries 30% dead audience, its real CPM is ~1.4x the quoted number. The fee doesn't change; the denominator does.

So what: reprice every quote against verified reach, then renegotiate to the adjusted CPM.
