But in the "new" news UL writes:
"Cyando entirely omits the 'Pay per Download' affiliate model and puts faith in its strong customer base, in return, the revenue you'll earn for leading customers to our platform was increased from 3 EUR to 7 EUR per new customer."
Yes, from now (1st April) the PPD system is freezed "until new advice", so now you can't generate earnings with downloads in UL.to, BUT in the email they said that will pay the requests of payments (earnings generated before 1st April) from the uploaders.
