This debate has been around for a while but one suspects that there will be concerted efforts now to compel major social media outlets to take action. The difficulty is that action is easy to ask for but harder to implement. Social media channels diversify and evolve and there are always new outlets. By definition their reach is pretty much limitless unless severe controls backed by legislation are put in place. I doubt few want that so the providers and the wider communications industry need to embark upon a process of review and creative thinking. The needs of Governments, the wider society and the 'international community' will need to balanced through the strategic plans of the providers - this is a monumental task for the social media providers but one they cannot shirk.
