Facebook wants you to know that people care about you. That’s the message coming from the social networking company’s Chief Security Officer Joe Sullivan, who penned a post on Wednesday asking those who may be thinking about suicide to know that that there are resources to seek out help. Seeking out ways to better protect its 1.15 billion users is more than a duty for Facebook — it has an obligation to protect its users, at least virtually-speaking. As the world’s largest social network, it’s a community of users who interact with each other across all facets of life, whether it’s for school, work, family, professional, or personal needs. But, with the rise of cyber bullying and other forms of digital harassment, the company must constantly be vigilant and work to help prevent suicide.
