Not a safe platform. Customs fees (duties and taxes) are for the recipient to pay in the recipient's country, however, creators are allowed to: keep your pledge and KEEP THE FEES THAT YOU ALREADY PAID SEPARATELY TO THE CREATOR "FOR SHIPPING" (which does not update the shipping fees on the pledge section on the campaign on Kickstarter); and REFUSE TO SHIP YOUR REWARDS if you don't agree to pay additional "customs fees" DIRECTLY TO THE CREATOR, INSTEAD OF YOUR COUNTRY as per normal regulations.
