"We are exploring a feature for people to give us feedback about comments on public page posts", the social networking giant said in a blog post, according to USA Today. With the downvote button, users can signal if a post is "Offensive", "Misleading", and "Off Topic". At the moment, the button doesn't affect the appearance or ranking of the comment, post or Page for other users, and the test is only running for five per cent of English-language Android users in the US.
It's imperative to remember that Facebook keeps testing out new features on subsets of its users, and doesn't always bring them to life for mass consumption.
Facebook also wants people to know this isn't a "dislike" button. If this Downvote button gets positive feedback, then there's no reason why Facebook wouldn't roll it out to all the users in and outside of the US.
How can Facebook promote meaningful interaction between users?
In January, Mark Zuckerberg said that "video and other public content have exploded on Facebook in the past couple of years" meaning there is "more public content than posts from your friends and family". He wants to do this by "protecting our community from abuse and hate" and "making sure that time spent on Facebook is time well spent".
Research showed that most Facebook users (64%) approved of the likely change with 25% strongly approving of the new icons.
While this feature is making headlines, some people have linked this with Reddit's famous "Downvote" button.
Instead, the Menlo Park, California-based company offers the reaction options allowing users to respond to the posts with different emotions such as love, wow, haha, angry or sad emoji.
It was first spotted by users who noticed the button next to "like" and "reply" buttons.
If your comment receives a down-vote, you will not be told but the information will be sent to Facebook.
Facebook wants to make sure that it is clear that the downvote button isn't a dislike button.
That could eventually lead to a way for Facebook to bury these comments, or the people that post them.
