What the hell? Why an FIR for selling an account? I seriously didn't know if account was hacked or not. I bought it for 0.2 BTC. I am nowhere related to hacking that account. Please don't do this to me. I am just a kid and haven't scammed him. I did pay back 1 BTC to robinson. Please don't do this. I need to study. Please forgive me. 
If you need to study then you shouldn't spend most of your time on here trying to scam people. You and your friends have scammed multiple times across multiple accounts and I think you'll likely continue if you manage to weasel out of this. Sometimes you kind of scammers need a warning from the police in order to get you to stop.
