Facebook wants to make it easier for blood banks to find donors.
The world's largest social network said Wednesday it's rolling out a tool in the US that allows users to sign up to be a blood donor and receive notifications if a nearby blood bank needs help.
The feature was introduced in 2017 but released first in India, Bangladesh, Pakistan and Brazil.
The move highlights how Facebook is trying to show it's a force for good even as it grapples with a seemingly endless list of scandals including around user privacy.
Hema Budaraju, Facebook's director of product for health, said that many people aren't aware if an area has a blood shortage or when, where and how to donate.
The social network wants to raise awareness while making it more convenient for people to donate blood.
