WhatsApp is beefing up security for community users as it introduces a way for people to hide their phone numbers from others.
Normally, the names of participants in a community chat are hidden from one another. Admins are the exception, of course, as they’re privy to the names of everyone. But, as WABetaInfo explains, if you were to react to a message in the community announcement group, your phone number suddenly becomes publicly viewable, losing your anonymity. With the aptly named Phone Number Privacy feature, that is no longer a problem as you’ll be able to hide your contact information from prying eyes.
