Answered my own question.  I did not find a vsftpd directive to do 
this.  But I was able to find fail2ban in the repos.  It was fairly easy 
to configure and I have been able to test and make sure it will have the 
desired result.  (My laptop is on lockdown right now!)

I still have no idea why the sudden interest in my little ftp server, 
but I'll worry less.
