Activision recently updated the Call Of Duty: Modern Warfare 3 "Code of Conduct" to combat anti-toxicity and disruptive behaviour. Included in the same blog was a breakdown of the game's moderation systems - revealing how the situation has improved in the multiplayer component of the game over time.
According to the data, there's been a "50% reduction" in players exposed to "severe instances of disruptive voice chat since the game's launch. Adding to this data is an 8% reduction in repeat offenders since the initial rollout of in-game voice chat moderation.
The blog also notes that "more than 2 million accounts" have seen in-game enforcement for disruptive voice chat so far, based on the Call of Duty Code of Conduct.
Activision's data showed only 1 in 5 users were reporting bad behaviour and to encourage more reporting, it's rolling out messages of thanks, and intends to provide players with additional feedback when acting on a report in the future.
Here's the updated part of the code "Treat everyone with respect", which aims to better combat the game being used to promote discrimination or violence:
"We do not tolerate bullying or harassment, including derogatory comments based on race, gender identity or expression, sexual orientation, age, culture, faith, mental or physical abilities, or country of origin, or the amplification of any person, agenda, or movement that promotes discrimination or violence based on the above.
All members of our community should be treated with dignity and respect.
Communication with others, whether using text or voice chat, must be free of offensive or harmful language. Hate speech and discriminatory language is offensive and unacceptable, as is harassment and threatening another player."
