Their business model depends on operating in a way that's nearly impossible to effectively moderate, and abusive (see all the stories about what Facebook moderators have to see) to try. The only way to fix the problem is to... not operate the business that way, since it's fundamentally a bad idea, considered from that perspective. Which would effectively mean the death of the company, unless they found some totally different and similarly-profitable business model they could transition to.
