I just discovered that #WhatsApp doesn't completely encrypt the list showing members of a Community. This means that third-party apps like #Beeper can display the number of people in a Community along with their profile pictures, allowing you to identify individuals if they have a profile picture set. Phone numbers appear to be obscured with random digits.
