Some of you may have seen that we're testing a new button next to comments on Instagram — this gives people a private way to signal that they don't feel good about that particular comment. I want to be clear: this is a test. There is no dislike count, nor will anyone know if you tap the button. Eventually, we may integrate this signal into comments ranking to move disliked comments lower down. Our hope is that it might help make comments more friendly on Instagram.
