Definition
A shadow ban is a restriction imposed by a platform on an account or its content without notifying the account holder: posts, ads, listings or profiles are quietly suppressed in reach or hidden from other users while still appearing normal to the account owner. The account is not disabled and receives no policy notice, so the owner may take days or weeks to realise that engagement has collapsed because the platform has limited distribution.
Platforms use soft, undisclosed restrictions as a middle option between doing nothing and a hard ban: for borderline policy cases, for accounts under review, for suspected coordinated or low-quality behaviour, and to limit the value of ban-evasion by not confirming to a bad actor that they have been detected. In advertising specifically, a shadow-banned ad account may still spend but at throttled delivery, higher effective costs, or with ads that serve almost nowhere.
In context
For media buyers, a shadow ban is diagnosed by symptoms rather than a notification: impressions drop sharply with no change in bid or budget, delivery becomes erratic, cost per result climbs across every campaign on the account simultaneously, or new ads sit in review indefinitely. The correlation across the whole account — rather than a single campaign — is the tell that the account itself, not the campaign, is restricted.
Responses depend on the cause. If the restriction follows a policy edge case, cleaning up creatives and landing pages and waiting out a review period can lift it.
If the account is simply distrusted, buyers often move spend to a healthier account rather than fighting an invisible limit. Because shadow bans are undisclosed, there is rarely a formal appeal, and experienced buyers treat account health as a portfolio problem — maintaining several accounts, watching each for the telltale account-wide degradation, and shifting budget away from any that show it.
Worked example
A buyer notices that across all five campaigns on one ad account, impressions have fallen 70% in two days with no bid or budget change, and two new ads have been "in review" for 40 hours. Other accounts running the same creatives are unaffected.
The buyer treats it as an account-level shadow restriction, pauses the account, and shifts the campaigns to a healthy one.
