Facebook Inc's on Wednesday changed the privacy settings on its WhatsApp messaging platform, allowing users to decide who can add them to chat groups.
The company said the setting will be rolled out today for some users and be available worldwide in the coming weeks.
This announcement comes amidst growing discontent over the world's largest social network's approach to privacy and user data as well as increasing concerns over its advertising practices.
The user inviting another to a group will be prompted to send a private invite through an individual chat, giving the recipient the choice of joining the group. The request will expire in three days.
