There are some people who never bring anything positive to your life, but noise and hatred. It might happen everywhere and, of course online, it's exacerbated. It'd be really useful and healthy to have a way of preventing comments from some people to show up while you're enjoying SN.
Of course, ignoring those comments is the way to go, but it's time consuming to even have to see them, hide them, and go about your life, so is there any way to prevent them to show up or any plans to add it some time in the future?
