What does it mean when your account is suspended?

My good friend let me borrow her account to ask this Вопрос I am actually @buffyl0v3r44
I don't understand I know for a fact I did absolutely nothing wrong and my account got suspended, could someone please help me? I worked really hard on all my medals, props, and Фаны and now I realize that all my hard work and dedication was for no reason, it isn't fair.!
