I copied the server IP, where Clara was recently playing ( I looked up for her on the internet as I am curious why she is playing GTA, but not showing up in the server. Thus, I heard a story about her getting mad ) to my favorites. 15 minutes after this, I am typing the /roadblock cmd before entering the vehicle. So what I did to make my life easier was to type /roadblock, ctrl + a, and little did I know that I didn't copy the text. And the result was I got banned for advertising, which I didn't intend to. I apologize for my stupidity.
