Well i can say that there is not a pathway to send EOS to the crowdfund (EOSCrowdsale) and its definitely not related to EOSdac. The only thing EOSCrowdsale if for is buying EOS. All it does is receive ETH (you send them Ether) and it allows people to claim the EOS they just purchased (using ETH) at the end of each 23 hr period. I am sorry you sent your EOS somewhere in pursuit of an airdrop. Don't fall for this again, no decent airdrop will ask you to move your coins to claim a drop. Where did you get this plan? EOSdac has nothing to do with the smart contract functions related to the EOSCrowdsale. It may be possible (though i haven't heard any success stories) to get incorrectly sent coins returned, but blockone would likely have to create a custom contract (or do it manually) and decide to return them.

The EOSdac drop only required holding your EOS in a location where you have the private keys.

I am sorry again! Make sure to be more careful (there were tons of articles online about all this) before sending coins places for unclear purposes.
