Serial DDoSers tend to have about the same level of computer knowledge as your parents. They just buy/rent botnets or pre-made software and templates to spread botnets. And that's for the people actually hosting the botnet or "booter" (which seems to be what the parent poster found). Most of the time, it's one more layer down: just some kids paying for the right to enter an IP to DDoS temporarily.
