Modern Warfare 3 developer Infinity Ward is handing out 5,000 day bans to a number of those found guilty of non-specific “bad” things – presumably cheating.
The ban effectively means that users will not be able to access the game with the associated account until the latter half of 2025.
The bans, word of which has spread online, were confirmed by voice of Infinity Ward Robert Bowling on Twitter, who stated: "If you see this message, it means you've been Permabanned (for something bad)."
It hasn’t been confirmed exactly what deeds warrant the harsh penalty.
Of course, there’s nothing to stop offenders re-registering under another name, though at least next time around they may be less likely to cheat.
