The article talks of WhatsApp, but I have received these weird messages via iMessage on my iPhone as well. I'm not sure if that's because I have a really old iPhone (iPhone 6). I generally block these numbers. It would be good if iMessage could create a "fraud/spam" marking for a message/contact similar to what email has today. WhatsApp seems to have a "report" button. fwiw - I have received more weird texts on iMessage and very little on WhatsApp. I've also noticed that these scammers may have access to data from other sources as well. I'm moving at the moment and out of the blue receive a call asking me if I have a house to sell. I just said no and cut the call. But there is most likely a massive data gathering operation behind the scenes as well.
