I just joined Steemit about six months ago, but only recently started posting frequently. I wrote Heavy's Blue Whale Challenge story you referenced here, and just wanted to thank you for sharing this with the Steemit community and alerting parents about the dangers. I know it's odd to get a comment 2 months after a story was posted, but I just wanted to thank you. It's so important to warn people about the dangers of this game. People are still finding my story, even months later, because the game is apparently still circulating widely. :(
