I've been hearing of this Pi Network for years and there is no indication that it is a scam. Even though the recent listing in Binance I think, is an indication that mainstrem exchanges are recognizing its potentials. Although I wouldn't bank on that, the fact that this post that alleges it is a scam was made 5 years ago and there is still no evidence that shows it is, is a testment to its resilience. Since the founders are known, we should just wish the project well.
