Dark posting
A dark post is an ad published from a creator's identity that never appears organically on her profile. Brands use it to run many targeted variants without flooding her feed. Because her face fronts content her audience never vetted, creators should contract approval rights over dark variants, not just the original asset.
Worked example
One approved video becomes six dark variants with different hooks, each targeted separately — none visible on the creator's own page.
