Online users who have received messages claiming their WhatsApp Messenger accounts will expire are asked to delete the messages and should not follow the instructions in them. This is because WhatsApp accounts do not expire and the messages are fakes that are being sent by cybercriminals to their potential victims. The fake messages or phishing scams are being used to trick potential victims into clicking the link within them, which will take them to a fake WhatsApp website where they will be asked to purchase a WhatsApp Messenger extension that doesn't exist.
