A recent update to the Facebook news feed is the introduction of a hidden unlike link. Facebook has added an unlike page button in the remove post drop down.
There are a lot of times when a user doesn’t like some of the content on the news feed. For this reason each post or entry on the news feed fancies a cross button on the top right, clicking on which shows options like. Hiding that particular post, Hiding all posts by that user or page and marking the post as spam. A recent silent update to the Facebook news feed has added an unlike button to that list.
I have a feeling this could really have a downfall effect on a lot Facebook pages. News apart, I would never dislike Manchester United, just saying.
