Facebook to restrict comments on public posts

Politicians, celebrities and news outlets will be able to control who can comment on their public Facebook posts under a new measure by the social media giant aimed at limiting defamatory or otherwise unwanted views posted by users.
The new product announced by Facebook will look to resolve this issue by giving users, such as news outlets and high profile figures, the ability to restrict comments on posts.
Comments can be limited to friends of a particular Facebook page or to profiles or pages specifically mentioned in the post.
