Facebook just started testing a new feature called “Keyword Snooze”. This feature will allow users to avoid or delay the spoilers in the News Feed of the Facebook app. Currently, it is in the testing phase so it is available for selected users only.
All the testers who want to use this feature can go-to upper-right menu of News Feed section of the app and use this feature to snooze specific keyword for the maximum of 30 days. Once the user selected the keyword, all the post containing that keyword will be pulled off from the News Fed section of the user.
This can be a good move from the Facebook to allow users to avoid spoilers in their News Feed but this does not guarantee that user won’t get any spoilers but it will surely minimize the chances of getting the spoilers.
