Facebook is tweaking its News Feed algorithm again.

This time, the social network is making adjustments to make it easier for people to ignore certain types of viral posts that may appear in their feeds.

The change is happening due to a relatively new type of feedback the social network has been collecting called “story surveys.” The feature, which Facebook says is surfaced to “ten of thousands” of users a day, asks users to choose between two viral stories.

Facebook notes that the change could particularly affect stories about hoaxes, which are often shared a lot and receive a lot of comments. Typically, a post that is shared and commented on many times would appear higher in a users’ News Feed, since shares and comments are taken into account by News Feed’s ranking algorithm.
