These kind of messages are often circulated on WhatsApp. There is no source confirming this. This would be violation of right of privacy at least if they did that openly. Even NSA doesn't do this openly. Plus imagine the computing power required to monitor so many accounts. NSA as well focuses on only looking at keywords in the huge data, rather than an algorithm where accounts are monitored. Accounts are then monitored only for those who are flagged.
