Limited Matchmaking has been implemented across all Call of Duty titles since Modern Warfare (2019), impacting players on console, PC, and mobile platforms.

A Shadowban in Call of Duty results in Limited Matchmaking, which restricts players' access to regular matches.

When players are suspected of violations, they are placed in a separate matchmaking pool while their accounts undergo review.

Players can recognize if they are Shadowbanned by experiencing longer matchmaking times, increased ping, and limited access to certain game modes.

The severity of the Limited Matchmaking status varies, depending on the nature of the offense, which can range from minor violations to extreme offenses.

Offenses that lead to Limited Matchmaking can include minor violations, temporary suspensions lasting from 48 hours to over two weeks, and permanent suspensions.

Actions that may trigger Limited Matchmaking include extreme violations, spoofing, circumventing security measures, and using unauthorized software.

Cheating and hacking are prevalent issues in online games, particularly in the popular free-to-play title, Call of Duty: Warzone.

To combat these issues, Activision employs the RICOCHET anti-cheat system, which includes kernel-level drivers designed to tackle hacking.

In addition to the anti-cheat system, Activision utilizes Limited Matchmaking to further enhance player experience and maintain game integrity.
