Shadowban in Call of Duty: What Limited Matchmaking Means

"Shadowban" is a player word. Activision's Security and Enforcement Policy does not use it. The closest official penalty is called Limited Matchmaking: the account stays playable but is placed in lobbies with other accounts in a similar state.

The policy page and the ban-appeal page were read on 2 November 2026. They apply to Modern Warfare 4 (released 23 October 2026), Black Ops 7 and Warzone alike, because the policy ties active enforcement to the Activision account and applies it on every device linked to it.

What the official policy says

• Accounts in limited matchmaking may be placed in lobbies with other accounts in a similar state.
• Party members can be placed in limited lobbies too while they are partied with that player.
• Players and their party members may not earn progression in those lobbies.
• At any time the account may return to normal matchmaking, be placed in the state again, or receive a temporary or permanent ban or other penalties.
• A separate penalty, Ranked Play Restrictions, can last for the rest of a season, carry across several seasons, or be permanent across future titles.

The detection side is described as client and server detection, monitoring of applications running during play, behavioural models and hardware validation. Activision adds that detection methods are validated by the security team before enforcement, and that reports by other players may support enforcement. Reports alone are not described as a trigger. The same policy lists Malicious Reporting, meaning knowingly false or spam reports, as an infraction.

Limited matchmaking and an attestation lobby are not the same

Since Season 04 of Black Ops 7 (patch notes of 3 June 2026), PC players who fail Microsoft Azure Attestation are placed in a separate matchmaking pool. That pool is small, so access is limited to Nuketown 24/7 in Black Ops 7 and Battle Royale Casual in Warzone, and these players cannot match with compliant PCs or console players.

To pass, a PC needs TPM 2.0 and Secure Boot enabled. The notes add that some AMD TPM software versions in the 3.x.0.x range can fail the check, and the fix is a BIOS or firmware update. A party also fails if any member's PC is non-compliant, with a message saying so.

This is a settings problem, not a penalty, and it can look similar from the player's side: few playlists, long searches, strange lobbies. Check it before assuming enforcement. Activision's Secure Attestation Wizard, described as recently launched in the 8 January 2026 notes, tests a PC against the requirements.

What cannot be confirmed from the outside

Many guides give a ping figure, a queue time or a duration, such as a number of days. None of these appear in Activision's policy or notes, so they are not reliable tests. The appeal page shows a status label such as Limited Matchmaking, with no reason and no end date.

Signs that fit limited matchmaking but also fit other causes:

• Searches much longer than usual in a playlist that is normally fast.
• Lobbies where cheating is common.
• Progression not counting.

What you can do

1. Rule out attestation first: confirm TPM 2.0 and Secure Boot, update BIOS if AMD TPM errors appear, and run the wizard.
2. Check status on the Activision ban-appeal page. It shows account enforcement status.
3. Do not file an appeal for limited matchmaking. The page states that temporary bans and accounts in limited matchmaking cannot be appealed, and only permanent bans may be.
4. Remove anything the policy lists as an infraction: unauthorised software, unsupported peripherals such as unapproved input modification devices, and spoofing tools. Detection of unauthorised software can close the application automatically.
5. Secure the account. The account holder is responsible for any infraction on it, whoever was playing, and bans are overturned only when the account was hacked.

FAQ

Is a shadowban real in Call of Duty?

The effect is real, under a different name. Activision's policy lists Limited Matchmaking as a penalty. The word shadowban itself is not used in the policy.

How long does limited matchmaking last?

Activision gives no duration. The policy only says the account can return to normal matchmaking or receive another penalty at any time. Figures quoted in guides are not from Activision.

Can I get limited matchmaking because other players reported me?

Reports may support enforcement, according to the policy, but detection methods are validated before enforcement. False mass reporting is itself an infraction.

Why am I only seeing one playlist?

On PC this can be the attestation pool: players who fail the check are limited to Nuketown 24/7 in Black Ops 7 and Battle Royale Casual in Warzone. Enable TPM 2.0 and Secure Boot first.
