When was the last time a site got taken down because "others think it is not acceptable"? Please, name a single one. There's a difference between people simply "not liking" a site, and people using extremely well-established principles of ethical concepts and human rights (which have been refined over centuries) to decide what content is violating the "laws", as we call them, which have been generally agreed upon in modern society. Further to that, hosts have what we call "terms of service" or "acceptable use policy" which clearly define what content is acceptable for that host to continue to serve the customer operating the site and administrating its content. Again, not someone "thinking it is not acceptable".
