While Facebook is built around finding friends over things you like, a new app has been built on the opposite idea. The EnemyGraph Facebook application encourages users to find things they dislike, or hate, to find people with common interests.

With nearly a billion active monthly users, the sites strategy is seemingly in line with the wants of the masses, reports BGR, who discovered the app. Others disagree.

The app was developed by Bradley Griffith, a graduate student, along with web and mobile developer Harrison Massey.

EnemyGraph is an application that allows you to list your enemies. Any Facebook friend or user of the app can be an enemy, the blog post - over at deanterry.com - says. The app allows people to makes pages or groups enemies, resulting in users finding common interests over what they love to hate, even allowing enemies to be set as archenemies.

The app works by finding people who have common enemies, and offers to start a conversation.

EnemyGraph runs what we call dissonance queries ... Relationships always include differences, and often these differences are a critical part of the fabric of friendship, the blog goes on to explain. Facebook currently ignores what people hate despite a demand for a Dislike button.

Currently, the most hated people or objects are Republican presidential candidate Rick Santorum, Internet Explorer 6 and cigarettes. The result is that people reveal information about themselves that Facebook previously didn't allow.

What about people who want to abuse the app, or take enemies outside of Facebook?

If you are not friends with someone else, or not a user of the app ... you cannot be listed as an enemy, the blog says. The post also confirms that the team will be monitoring users for abuse.

If users want to get in on the app, though, then do so. The team predicts that Facebook will shut the app down very soon.

We give them [Facebook] a couple of weeks at best before they shut us down for broadening the conversation ... EnemyGraph is a kind of social blasphemy, the blog predicts.

Reading Facebook's FAQ on reporting abuse, the company is keen to highlight the Report link throughout the site. For EnemyGraph, that could be bad news if it becomes popular and users take information outside of the app.

Facebook has been built on finding common interests and likes, causing it to look towards its Initial Public Offering. Apparently the company is looking towards a May window and a $5 billion valuation, say Bloomberg's sources.
