WhatsApp and Facebook Messenger scam sees people told to pass on message to avoid having to pay

WhatsApp and Facebook Messenger users are being tricked into sending out a message by a scam. The hoax claims that people need to send out a message otherwise theyl'l be forced to pay for each one they send to their friends in future. If they don't copy and paste the post then the apps will presume that they are not an "avid user" and so will move towards charging them, the post claims. But it's entirely untrue and neither Facebook or WhatsApp is moving to charging for messages. Both are expected to remain entirely free – which they need to do, since Facebook's business model is capturing information on its users and then using that to charge advertisers for marketing.
