WhatsApp uses a new feature to reduce the spread of misinformation on your platform. The update notifies users if the message has been retrieved multiple times.
If a user tries to forward a message that has already been forwarded, WhatsApp will notify users that it will be marked as "forwarded multiple times".
A user can continue to send the message or choose to quit. To recall, a “frequently forwarded” label was anticipated for WhatsApp, but the feature seems different since the label on messages that have been forwarded many times will continue to say “Forwarded” but will have a double arrow icon.
