Unlike Bitcoin, Nxt presently relies solely on brainwallets as the means of user authentication. There is no "cold storage" alternative offered.
Type anything like

Save it and use as a cold storage passphrase.
The account (16025050820116515852) has 0 coins. Wait a few days and we will probably see something there lol!
We should fund all the accounts of known passphrases with 1 NXT to prevent the use of it.
How about kill two birds with one stone?
Create a script to send 1 NXT (with 1 more NXT as the tx fee) to the addresses created by the dictionary from the unclaimed account every minute. The tx fee can help to increase a little bit incentive of mining.
Moreover, this can be a good penalty to those unclaimed owners. This is a great idea!
Sending one Nxt to accounts with bad passphrases wouldn't do anything. It wouldn't lock the accounts or prevent people from using them. On the contrary, it would probably encourage individuals to use those accounts with bad passphrases because they would get one free Nxt.
He cannot use this 1 nxt since each transaction needs at least 1 nxt tx fee.
Once they deposit more Nxt, he can use that additional Nxt. I know your intentions are good, but where would you come up with all that additional Nxt? There are tons of single words, common phrases, words with a few numbers added, etc which unlock accounts that you'd have to send one Nxt. Also, Nxt should be in accounts that PoS mine to increase network security and not in unused accounts.
