Facebook announced yesterday that the company is planning to cleanup the News Feed by reducing stories that users report as spam, or dislike. The cleanup targets three categories of News Feed spam: Like-baiting posts, frequently circulated content, and spammy links.

Some posts simply ask people to Like, comment, or share, in order to get viral. This is popularly referred to as Like-baiting, and results in the posts getting shown higher up in the News Feed. These stories are not only less relevant but also lead to a less enjoyable Facebook experience, the company says.

The new update will better detect these stories, and will make sure that they are not shown more prominently in the News Feed.

Another type of spam Facebook will target is frequently circulated content. The company says some content appears in users' news feeds too often, and it's looking to de-emphasize pages that share the same content again and again.

Lastly, Facebook says that it will also target stories that use inaccurate language or formatting to try and trick people into clicking through to a website that contains, for example, only ads. The company plans to do this by measuring how often its users, who visit a link, choose to like the original post or share that post with their friends.

The changes won't affect those who are not posting feed spam. They may instead see a small increase in News Feed distribution, the company said.
