I will check out the stories, I love sci-fi. I have tried to get on discord before, but I can't make it work over TOR, even with bridges, which is problematic. @stevescoins has been keeping an eye open for an anonymous solution, if you think of one, I would be happy to hear of it.
I have written a number of pieces that deal with issues also explored in Black Mirror that might interest you, though not all draw an explicit reference to the show: Call of Drones, Your Digital Clone Can See the Future, The Slow Creep of Scientific Dictatorship, Cyborg Chickens and Welcome to the Machine.
I'll keep an eye out to see if there is an anonymous way to interface with discord. I look forward to reading the links you shared!
