He justified his decision of not including a dislike button by saying that it can fuel hatred on social media. But, it looks like the Facebook users are going to get the much-awaited dislike button. Well, sort of.

Instead of rolling out the feature for posts in your News Feed, the company is teasing the feature in Facebook Messenger, as reported by TechCrunch.

Suicide is the second leading cause of death among 15- to 29-year-olds -- and Facebook wants to leverage artificial intelligence to help with prevention.

The company announced Wednesday it is testing the ability for AI to identify potential "suicide or self injury" posts based on pattern recognition from posts that have been previously flagged on the site in the past. Its community operations team will then review the posts to decide if Facebook should surface crisis resources to the user.

The social network twice disabled the account following complaints, only to re-enable it hours later.

"These posts are clearly distressing for the families and this content has now been removed," a spokeswoman said.

"We apologise for the delay in taking them down."

The social network acted for a third time after the matter was brought to its attention by the BBC. It has not explained the actions of its complaints team.

One internet expert said the behaviour had been "bonkers" and called into question Facebook's safety procedures.

According to a study from researchers at the University of Maryland, almost 70% of people who attended the D.C. march heard about it on Facebook (FB, Tech30). Meanwhile, 61% from friends and family.

Choose an emotion instead of just a like, and your friends get a better sense of how you feel about their posts. But doing so also tells Facebook something about you.

And that is one big reason Ben Grosser, an artist and a professor at the University of Illinois, who describes his work as "writing software in order to investigate the social effects of software", made an extension that randomises what you tell Facebook about how you're feeling.

It's called Go Rando, and - I'll be honest - it made Facebook likes a little terrifying for me when I first installed it.

In a letter describing the plan, he said algorithms would eventually be able to spot terrorism, violence, bullying and even prevent suicide.

He admitted Facebook had previously made mistakes in the content it had removed from the website.

But he said it would take years for the necessary algorithms to be developed.

The Signal app, which is widely considered the most secure of all other encrypted messaging apps, released video calling feature on Tuesday for both Android and iOS in a new update.

Developed by open source software group Open Whisper System, Signal is a free and open source messaging application specially designed for Android and iOS users to make secure and encrypted messages and voice calls.
