Facebook seems to be attempting to respond to the most recent round of criticism against it and deflect from it by “doing more” with an announcement that new censorship measures are on its way.
This time they concern groups, whose members’ posts will be demoted if Facebook determines that they had violated its guidelines in other places on the giant network – meaning that their group-posted content can still be in line with Facebook’s rules, without having broken any. The downranking will apply to all content posted by these users in a group.
