As per today, 8 days after I requested payment from StockXpert, there's a new message on my account page, saying "Next Moneybookers payment: March 8". That means at least 10 days to get paid from StockXpert.
On their FAQ page, it says: "We try to do our best to process payment requests within 3 workdays, but sometimes when there's a surge of requests this may take longer. Payments via Paypal, Moneybookers and such should arrive instantly."
While they take only a couple of hours to approve or reject photos, paying photographers is apparently not nearly as much fun. This sucks big time if you ask me
