I easily slipped toxic language past Alphabet's machine-learning-powered comment detector

On Thursday Alphabet released a machine-learning-based service, called Perspective, intended to identify toxic comments on websites. It's from Jigsaw, a unit working on technologies to make the Internet a safer and more civil place. But when I toyed with Perspective, the results were erratic. Perspective rates comments on a 1 to 100 scale for "toxicity," defined as "a rude, disrespectful, or unreasonable comment that is likely to make you leave a discussion." "Screw you, Trump supporters" is judged to be highly toxic, while "I honestly support both" is not, for example.
