When my girlfriend recently tried to access Craigslist on her French dorm's internet, she got this instead:
According to the current security policy, the URL you have requested is blocked. Host : 'www.craigslist.org' URL : '/...' Categorie : 'Pornography and Sexually-explicit Content'
Weird.
Maybe somebody should have told them that regex-matching agains three-letter words is not exactly the best method of keeping your students from surfing around on "dirty" websites?
The page she wanted to see was a harmless "best of craigslist" story after all -- I doubt it would survive long on Craigslist otherwise.
