You wouldn't actually need to pay the money. You'd just need to make sure it got pre-authorized. Then once you got another legitimate pledges you could withdraw your fake ones (or leave them up but without any money in the accounts, I believe it's fairly common for KS not to be able to collect al the pledges at the end)
