Pacing rails

The pacing mechanism is shared and Instagram's numbers are deliberately unset, so there is no daily cap and no enforced cooldown on the Instagram side today. What limits Instagram engagement instead is the room: an exchange is closed until 7 creators are ready, a campaign is capped at 10 points, and the grant is floor(0.75 × (N − 1)) rather than unlimited. TikTok, which launched with the mechanism, has all ten of its rails set and publishes each one with the config key that sets it.

That is worth saying plainly rather than leaving to be discovered. A reader who finds out elsewhere that Instagram has no daily cap has caught this site in a claim; a reader told directly has been given a fact about a platform that has run without pacing since it launched.

The room. An exchange is closed until 7 creators are ready, so there is no all-day open tap.

The campaign cap. A single campaign takes at most 10 points.

The grant. A room of N grants floor(0.75 × (N − 1)) engagements, not N − 1.

The health score. Below 95, every point and every delivery waits 24 hours.

TikTok launched with the mechanism switched on and publishes all ten of its rails, each beside the literal configuration key that sets it and the method that enforces it. A number with no key beside it is a marketing claim; a number carrying the key that sets it is something anyone can check.

The rails are on the TikTok safety-rails page in full, and they are the reason that cluster is worth reading.
