Registrations will reopen for the airdrop on the 16th round, which is in 2 weeks. You can read more about it at the official DeepOnion forums:

My concerns with the new "auto accept" function of the airdrop registration is it's going to leave the door open for more abusers. Obviously, this isn't the intended case but if it takes no time or effort to get approved after your application is sent in why wouldn't people take a few hundred $ profit and gtfo?
