WhatsApp has shared a new update about how it prevents scams, as well as unveiling a new feature aimed at protecting users from possible swindles. People will now receive alerts when they are added to a new WhatsApp group by someone not in their contacts.

In a post, the Meta-owned service says it took down more than 6.8 million accounts linked to scam networks primarily based in Southeast Asia. WhatsApp said that many of them are driven by cryptocurrency investment scams and pyramid schemes, and that some use ChatGPT to generate text and links that may send users to other apps.
