Not all Twitter bots are racist -- some are genuinely creepy, (but in the best possible way). Take @smilevector, an algorithm created by New Zealand neural network researcher Tom White. If you submit a photo of your favorite celebrity in a glum or neutral pose, it'll turn it into a bizarre, "I just ate a child" kind of grin. The bot "uses a generative neural network to add or remove smiles from images it finds in the wild" or submitted to its follow list, according to its creator.
