Idiots. I'm really furious. There is a dedicated psycho in our neighborhood who sends threats of violence, murder, and rape to other players and the game tells him where those other people are in real time. It seems like a solution shouldn't be too hard but it takes months and months for him to even get an account banned (and then he's on a new one instantly).
Even the ability to block certain people from seeing your activity seems like a common sense move but apparently not. If you're not willing to oversee your own game and the safety of its players at least give them the tools to do it.
