Oh my goodness! It seems to be a trend around the world. In my country, Kenya, we have a paid-to-click ad scheme that has been around for just 3 months, 24 days. It is known as Public Likes. Just yesterday, disbursment of money to its users wasn't working. It has gannered 500,000 members. I have a feeling, just like the one you have mentioned, it will one day disappear.
