You may not have a proper conception for how anon uses DDOS. A single hacker may DDOS via creating a botnet of zombie computers infected via worm, trojan, or virus. However, anon just uses "LOIC", which is a client that people who want to participate in the DDOS run. There's a call for DDOS of a target, people run their DDOS clients and set the target, there's not necessarily any "hacking" going on whatsoever.
