Activision explains 'limited matchmaking' strategy for suspected CoD cheaters
The company uses shadow bans as a stop-gap measure to isolate suspicious accounts without risking permanent bans for false positives.
Activision is utilizing a specific isolation tactic known as "limited matchmaking" to manage suspected cheaters in Call of Duty. The strategy allows the company to remove suspicious players from the general population immediately while security teams conduct deeper investigations.
David Andrews, the Senior Director of Game Security for Call of Duty, explained that this system—commonly referred to by the community as shadow banning—acts as a critical stop-gap. According to Andrews, the process isolates accounts while other security checks are running or while the team awaits additional data. This approach is designed to prevent the "irrevocable impact" that a permanent ban would have on an account if the initial suspicion turned out to be a false alarm. Beyond isolation, Andrews noted that the system is also used as a tool for player rehabilitation in certain instances.
The Anti-Cheat Framework
This tactic is part of a broader effort to maintain integrity within the franchise, particularly in the free-to-play Warzone title. Activision employs the Ricochet anti-cheat system to detect and mitigate unfair advantages. Rather than relying on a single method of punishment, the company utilizes a tiered enforcement strategy. This hierarchy of penalties includes ranked play bans, remote play bans, temporary or permanent suspensions, and hardware-level bans to prevent repeat offenders from simply creating new accounts.
Balancing Security and Accuracy
The reliance on limited matchmaking highlights a persistent challenge in the gaming industry: the risk of false positives. Anti-cheat software must often distinguish between sophisticated cheating tools and legitimate software or unusual hardware configurations. By shifting suspected users into a limited pool, Activision can effectively neutralize the threat to the wider player base without the legal or customer-service fallout of an incorrect permanent ban. This creates a buffer zone where the security team can perform holistic reviews without compromising the experience of the general population.
Future Outlook
As cheating methods evolve, the use of tiered enforcement and isolation pools is likely to remain a core component of the Ricochet system. While the current framework provides a mechanism for rehabilitation and error correction, the company continues to refine its data collection to increase the speed and accuracy of its permanent bans. Players can expect continued iterations of these security measures as Activision seeks to balance aggressive enforcement with account security.
