Speaking of emotional attachment, I recall from what I had watched from some documentaries in Youtube about those scammers trying to manipulate elders. From my experience talking to some elders back when I was working in a call center, most of them were really kind hearted to the conversation. Now that I heard that there were some call centers operating a scam, it's sad that they're taking advantage of these elderlies.
On the brighter side, there are scam baiters that are trying to destroy these scammers though.
