It would have something to do with your contract you're signing. The current one says something a long the lines of "you accept that you will be contacted when you have earnt $100USD for the month and if not reach will compound with the following month" SOMETHING LIKE THAT, not an exact quote. But from that they only have to pay you at $100 total earnings and if people dont see the money each month they might quit because of that and I dont know if thats a new contract because a lot of people are still reporting no payments :/ its a mystery to me
