BACKGROUND

WhatsApp users have reportedly been receiving spam messages from a foreign phone number, informing that their WhatsApp number was selected to win a prize. Users who block the sender's number would then have their WhatsApp account suspended for a certain period of time. Once their account is recovered, previous chat conversations might be lost if the user has not backed up their chats.
