I was approached out of the blue being told that I was supposed to receive a sudden windfall, someone opened an automatic trading account in my name, or offered to invest in a lucrative mining contract. A while later, I'm being told that there are now "thousands of dollars" waiting to be claimed by me.
However, when I try to withdraw the money, the operator asks me for an "advance fee" or an "unlocking fee" so that they can pay me out my money.
That sounds fishy, what is going on? What should I do?
