A new investigation by BBC Africa Eye has uncovered an audacious global pyramid scam run from Europe, using smart-phones to cheat ordinary people across Africa, Asia, and Latin America. Crowd1 describes itself as "the fastest growing crowd marketing company in the world" and produces social media videos that show members buying new cars and enjoying luxury holidays. Although the scheme appears to have made a fortune for a handful of European scammers, many of them Swedish, it has left behind a trail of debt and poverty in countries including South Africa, Kenya and Nigeria. For more on the ugly truth behind the shiny surface of Crowd1, Channel Africa's Lulu Gaboo spoke South African journalist Ayanda Charlie, who was involved in the six-month long investigation.
