I announced the project ten days ago, so it's been more than a couple. Although I can confirm that they're not all unique. I will do my best to remove any repeat submissions. I chose to do it this way to have the most fair airdrop possible, one that doesn’t exclude anyone (if I did it based on bitcointalk rank), or give more tokens to some people based on the amount of money they have (if I did it based on ETH balances). Each way has trade-offs, just know I'm trying to make it as fair as possible for you guys.
