> I just don’t get why a website would want to harbor a community that toxic. In my mind, the answer is quite easy: increasing the amount of page loads increases the amount of ads people see. If you deliver emails along the lines of "someone replied to your comment", people are gonna click on them and you're going to serve another set of ads. Moderation requires effort and reduces the amount of page loads, therefore most websites that use comments don't want to do that.
