I had 100% challenge completion and season pass, I won't be buying BO3 again. I completed everything in the game prior to being banned. I really do not see how I was banned on BO anyways, I was playing pretty legit. I was even using OP weapons to try to use the excuse of that the weapon was just OP, like the auto-shotgun.
As for CS:GO, I only look if I hear footsteps or if they shoot, even if they kill me, but I'll keep them in my mind in the corner of the screen. I even made a photoshop that my rank was Global Elite and put it on my Steam Profile to make it look like I was a super-smurf.
