I have received the exact scam on whatsapp. What the hell??
They claimed to be a banker (following the exact format from the exmaples in the blog) and I genuinely thought that they were a real person but even after I told them that they are texting the wrong number they kept forcing the conversation so I blocked them. A couple of months later they texted from another number but a different name but they continued the conversation from where we last left off.
Crazy reading the article now. I would have been devastated if I fell for it. I am usually very good at spotting scams.
