I don't know what Sony are doing about it, but I am still reporting these hackers / modders to Activision, so I say don't give up just yet
I will speak with online support tonight and see what they say and let you know.
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
Dont joke on me please, i mean i usually play mw2 about 6 hours a day (used to) because (sorry for this) fuckin hackers i mean there are at least 3 per game, at least, lately there are about 9 could you please stop this? or at least make a box in game to report them? a mod or something? please stop this i had stop playing because of them...
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
