Sure, but people get burned despite attempting to be careful all the time.
Translation software predates Google translate, and I'm not claiming something has suddenly changed. It's slowly gotten better, and I assume the temptation to only pretend to have human translation will keep growing with it. The safer a scam seems, the more people will try it.
How's your hypothetical any different now than it would've been in the past 15 or so years of Google Translate's existence?
