They are still banning. This is the most unsafe COD game to cheat on along with black ops 1 and 3, i mean people can continue using vsat hacks etc, and keep wasting £40 everytime.
It's their choice, but just know it's a guaranteed ban, maybe a day, maybe 2 months, i will never see the logic in paying $40-60 for a game then risking getting banned or making the game unplayable to which everyone stops playing it?
One day some one will get banned. buy a new account, login and there will be nobody online and it will be his/her own fault.
