isn't ddos illegal or some stuff
yes, as per US Title 18: Crimes and Criminal Procedues : Part 1 : Crimes: Chapter 47: Fraud and False Statements: Sections 1029 and 1030, as well as the Electronic Communications Privacy Act, Computer Fraud and Abuse Act of 1984, Cyber Security Enhancement Act of 2002, and some others, i'm sure. however, it's not immediately clear that this was a ddos attack and it's unlikely any legal action will be taken against vittoriohp even if it was found to be one.
