"Clearly we prioritize safety very seriously, as you can imagine. And some of it could be us being overly protective, a mis-moderation leaning on the side of being careful. Sometimes we have taken something down as an abundance of caution. The position of moderation is very important. It’s not only getting the violation rates down, it’s reducing overmoderation, which happens. It’s a price you have to pay, and you have to find the right balance."
