Never? The term "snake oil salesman" has been around since the 1800s and that's effectively what most of these growth hackers are. I'm sure there are plenty of terms for the same practice of fraudulent marketing that predate that by centuries or even millennia. If you can hype people up enough about what you're selling and get them imagining how much better their live's will be using your product a certain number will buy into anything (in DNPs case, people imagine how much time and money they'll save on not using a lawyer). I wouldn't expect that to ever change.
