Yes, today's You and Yours, was quite frightening. Mainly because many of the cases were not people being 'under a spell', but careful savvy people who knew the ropes and had made all the necessary checks, but were misled by, among other things, cloned websites for reputable banks.
However I listened to the prgramme yesterday and felt that the people there, intelligent but financially not knowledgeable people, did, at times, act very foolishly. I think they responded to a cold call, they did no searching to find out about the company, or even ask friends and relations about it and finally, encouraged to invest £100, when it grew to £400 in a week they saw this as encouragment to invest more. Surely most people would immediately be suspicious about such fast growth in such a short time and smell a rat, whether they were financiallknowledgeable or not.
