What are you talking about?

I just can not understand what the problem is at all, because I know that I did not use forbidden software (the so-called "cheats"), and I only have access to this account. nevertheless, you demand that I do something. why should I do this?

there are other ways of checking this, for example, I can add you as a friend to the origin, I do not want to perform the manipulations indicated there, because I think that this can have a negative effect on the security of my account.

why should I do this?

I go to see my statistics, understand what weapons are worth using and so on and see that I'm banned. To be honest, I'm shocked, for what reason? what does this mean: "Linked account"? this account was stolen from someone?
