It is funny how EA is willing to spend so much time and effort on resources to combat cheating. One simple solution below can solve wrongful bans and people on forums moaning about cheating.
Warzone has SMS verification every time you login to play. You get banned then that same mobile phone number is banned too from login. It is more hassle to go through getting new temporary mobile number in cost and effort than it is to create new gmail account.

Maybe outgoing SMS verification texts sent to millions of players logging in per month too costly for EA?
Or perhaps a smartphone app associated to mobile number to receive verification via data instead if it saves SMS cost?
Ban byWAN IP if you're on public network like campus, fixed leased line or cable connection that never WAN IP reassigns for months. That's tough luck
Or just let players complain forever. The rate of bans is lower than the rate of increase of cheaters, so problem increases over time
Prevention is better than cure.
