Call of Duty's updates account posted a blunt line about Modern Warfare 4's DMZ: item duplication glitches and the intentional abuse of exploits violate the terms of service, and enforcement action against accounts found exploiting them has started. It is the first time since launch that Activision has put abusing a bug, rather than running cheat software, in writing as grounds for action in this game.
Official. The enforcement line comes straight from the official Call of Duty updates account, and the official launch patch notes record the matching exploit closures on October 24 and October 25. What is not stated anywhere official is the penalty: no ban length, no reset policy, and no numbers. Treat the rule as settled and the consequences as unpublished.
Why Hardcore SnD cares
The post is framed around DMZ because that is where the duplication glitch spread fastest, but the rule it states is not written per mode. Search and Destroy spent the first two days of the game with a defuse exploit live: players could defuse the bomb from an unintended distance or position until the October 24 update closed it. Anyone who worked that out and kept using it on purpose sits inside the behavior this statement now calls actionable.
- A known bug is not a free pass Infinity Ward's line is that intentional abuse is the offense, not running into the bug. A round winning trick in a one life mode fits that description exactly.
- Scrims carry the same risk as pubs An exploit that steals a site in a pub steals it in a scrim too, and the account that takes the penalty is the one that used it.
- The fix cadence is the real defense Two updates in two days closed DMZ exploits and the Search and Destroy defuse bug, so the useful life of any single trick keeps getting shorter.
What is not spelled out
There is no published penalty ladder. The post does not say whether a first offense is a warning, a stat reset, a temporary suspension, or a permanent ban, and it does not say what happens to progress or items earned through a glitch. It gives no numbers either, so there is no way to tell whether this is a handful of flagrant accounts or a wave. Until Activision publishes a support article or a progress report, the consequence is a question mark even though the rule is not.
The rule is settled. The punishment is not published.
If something in a match looks like it should not be possible, the safe play is to stop using it and report it rather than farm it. The terms of service line now points at the player who keeps going.
