A game called Blue whale, mobile game that once you install it, it can't be deleted and it will gain all your personal information, locations, numbers EVERYTHING! It is not on play store, some of the creators message you, or call you on phone to get the game. Don't accept that call, nor accept installing the game. The game has 50 day challenge where every day it makes you harm yourself, in the end it forces you commit suicide. If you don't follow their rules, they threaten you, because they have all your personal information.
Nobody knows if this is fake or real. But if anyone encounters this, be aware. A friend of mine created the opposite of this in instagram, calling it Pink whale, and it teaches others to practice positivity. @pinkkwhale is the username.
Stay safe everyone!
