This is not interesting at all, do you think people will submit their document for free spins? Even worst the max winning capped at 0.01 only, is it worth to do KYC for non-guaranteed 0.01? I do even think people wont do KYC for pure 0.01 giveaway.
I'll be so surprised if you can get many people do above tasks for nothing.
Did you read the T&C careful? There has been mentioned
*Withdrawal will be denied if documents are not uploaded properly.Which means you doesn't have to upload your KYC when you get your free spins, you can upload it when you gonna cash out!
