Robert Bowling (fourzerotwo) will not acknowledge sheer volume of ppl using hacks on pc in mw3, he only logs into these forums to post updates in the general section of mw3. He does however pay a lot of attention to his twitter account, but will ignore many PC related problems, want a clean PC community? our only hope is with ranked dedicated servers, sure there will be some dedis where the admins etc use hacks, but just dont join these after you find out, favourite the ones that ban botters and taa-daa you got a clean community to play with where you can actually play the game to its full capacity ie lvl your guns and your account.
Without these we are left with steam and P2P, which if you google around can find some very disturbing truths. I learned from mw2 how bad this is and have already seen the mw3 version. With the P2P scheme, ppl can force host onto themselves, you have all probably seen this without knowing when a game lobbby remains at the waiting screen, the timer has counted down, you expect it to say launching, but remains on waiting for up to a minute.
Now for the dangerous part, when some1 has forced host onto themselves, there are other applications available to them to view every1 in that lobbies IP address (you dont want hackers knowing your IP address incase you didnt know). This can allow them to kick you from rooms, kill your steam connection and if they are good hackers do far worse damage to your internet life (dont use credit cards on same PC you play this game).
In mw2, the most common was mw2_liberation (google it), in mw3 theres one called mw3sa. these are extremely dangerous and unless you like hackers having access to your IP addresses, this has to stop. So bombard robert bowling's twitter account with requests for ranked dedicated servers !!!
The only reason i can think of as to a reason why he hasnt already implemented this is the possibility of ppl boosting and providing ppl with the all titles and emblems lobbies. but if you enter a lobby with every1 on lvl 80, you can assume its a hacked lobby, press ctrl+alt+del and bring up your task manager, find infinty ward processs and kill it, to stop it having any effect on your data. and really which bothers you more, some ppl using these to get all titles and emblems or the roughly 50% of ppl playing mw3 on P2P games having wallhacks, or worse, the dreaded aimbot.
If all goes well and we got clean dedi servers, we may see an increase in speed at which an elite form for PC could be seen.
