My Email was blocked due to profanity

I emailed something to the listesrv this evening. This is the message that I received back from a receiving school email: "This email has violated the PROFANITY. and Quarantine entire message has been taken on 8/1/2009"

The ONLY word in there that may have even come CLOSE to being profane was the word 'twit.'

Here's the line: "One way to do this is to have each twit.. er.. tweet :-) include a hash tag that you specify."

Am I the only one who thinks this is just WAY over the edge of reason?
