FTP Server Honeypots

An anonymous reader writes: I run an FTP server for a few dozen people, and it seems like every week I have a random IP address connect to my box and try guessing "Administrator" passwords once every five seconds or so. This poses no real risk to me, since all my accounts have custom (uncommon) names. But if this is happening to me, I would wager lots of people are at risk of low level, persistent, long term password cracking attempts. Is there a way to report the perpetrators, or any action we can take to address this kind of danger?

Tar pit them if you FTP server supports it. When someone attempts to log in using one of these accounts set to the timeout between username being submitted and the password request to be long. Then set the password acknowledgement to be long. It won't stop them but it'll slow them up a little and every little counts.
