The responsibility is not Facebook's I agree that Facebook has no legal responsibility here, but the responsibilities they have willingly to take on in the past does create an level of expectations in the userbase. The userbase is completely within their rights to try and exert social pressure on facebook. If Facebook chooses to actively prohibit adult content being shared between two adults, and monitors the content of private chat conversations, why shouldn't it remove this type of content when it comes to their attention? Is it unreasonable for users to expect them to do that?
