I spoke with them last night bud and was told that they have people looking in to these violators across all the COD titles, they also have members of there team in game catching people out.

All in all, sounds like they are trying, which is good

I am not joking with you, that is honestly what they said, if you don't believe me ask them yourself?

You can report players through the support section - https://support.activision.com

Just choose MW3 but in the ticket tell them it is in fact MW2 you are on about.

Hope this helps
