Until Facebook has AIs that can detect suicidal ideation from users' posts or the expressions of their faces on video, the social network will continue adding more suicide prevention tools. It even teamed up with a number of crisis and mental health organizations to provide support over its Messenger app. Now, the company has announced that The Trevor Project will also be on Messenger to serve as a suicide hotline for lesbian, gay, bisexual, transgender and/or questioning/queer youth. Teens might have Snapchat and Instagram, but some surveys show they haven't abandoned Facebook altogether -- the social network's partnership with The Trevor Project could help save lives.
