Yep. Cold calls, emails, texts, whatever they could get their hands on all through my senior year in high school and at least my first two years of college. Not to mention their tables in the high school cafeteria, at robotics competitions, my engineering university's job fairs. Don't remember how I got them off my back, I might have just aged out of their main target cohort, but my mom likes to talk about how she told them she was pregnant (because she was lol) and they never contacted her again. Do with that information what you will.
