These are no made up quotes, they sent it to me. The only conflict is that I had to use one stock image because that student did not send me her profile pic.

I was wrong in assuming any of the testimonials were fake. They're real.

That said, fake accounts on social media are legal. Fake testimonials aren't.

Reddit is one random success story and not indicative of whether something is ethical, where it concerns investors, or whether it's a good idea for a SaaS (a completely different model from Reddit).

You had an important point: the testimonial looked fake, and that makes people trust the product less.
