Hi my account was banned about 2 years ago from what I know the ban was given because of the use of some cheats I have never dealt with such a thing and my friend also played on this account. After a few years, I wanted to go back to bf4 and play like a normal person, but unfortunately I encountered such unpleasantness. I would ask for a positive consideration of my case because I am not a person who knows too much about cheats.
Ban is valid. Appeal to punkbuster, not us
