It's a very common scam. We'll send you 0.09558828 ($500), but you must first send us $50. Ask them to deduct the $50 from the amount they send you and see what lame excuse they come up with.
It's so funny. This is a marketing strategy legitimate businesses use. From time to time you have "cash back" discounts, where if you buy x product, they'll send you x amount back to your bank account afterwards. What really happens is that they have all your information and they can sell that to third parties for a decent chunk of money.
Scam sites added their twist to it by going a few steps further. It's so silly how people even take the time to ask people around them if this is a scam or not. How obvious do you want a scam to be in order to realize it is a scam?
