I'm not sure if you are familar with perl but perl has a pragma called Taint
that when enabled prohibits the use of user supplied input until the proper
input is regexed out of it - for example, usernames shouldn't have any
punctuation other than _ or control codes, etc.  I'm not sure exactly what
Python has in this regard as this is Day 1 of my Perl Recovery Program (*s*)
but its a mindset worth applying.
