OK, so. Amir has said time and time again that he can't ddoss, yet he has in the past which proves that he CAN ddoss. Even if this is all a stuffty joke by Amir, he still has the ability to ddoss.
Also, about the spying on servers thing with blhack. Like 4 times in the past, I have been able to 'spy' on servers I am banned on. I really don't know how, I dont have any malicious add-on, but I was able to join (and not see the player list, or spawn) and see chat, but not chat myself. It was all most likely extremely low chance with connections and stuff, but it can and did happen.
