Whatsapp Plus banned by Whatsapp

Whatsapp Plus is said to be the third-party extension to the original Whatsapp but the extension has some flaws according to Whatsapp themselves indicating the privacy concerns for using that. What Whatsapp does is to ban the users of Whatsapp Plus perhaps for privacy safety reasons or something. Sure, there might be encryption feature in Whatsapp recently like what iMessage and FaceTime were already having the same security level but then, it looked like Whatsapp Plus has been used by millions of customers and trying to ban them all for that reason is a difficult thing.
