Facebook is cracking down on fake 'Likes' that are being used by marketers, spammers and malware, reporters Reuters.
Companies can raise their profile on Facebook by purchasing thousands of Likes at a time, which is forbidden by Facebook. Many of these Likes come from fake Facebook user accounts.
Some marketing programs trick users into liking page when they perform another action, such as clicking to watch a video.
Many of the ad campaigns on Facebook are designed to gets tons of Likes to give the appearance that they have a large and responsive fan base.
Facebook said in a post on its official blog on Friday: "Newly improved automated efforts will remove those Likes gained by malware, compromised accounts, deceived users, or purchased bulk Likes."
"While we have always had dedicated protections against each of these threats on Facebook, these improved systems have been specifically configured to identify and take action against suspicious Likes."
Facebook said the number of Likes, or endorsements by users, on corporate pages is likely to drop by less than 1 percent.
