This reminds me of a story I heard about one of the earliest ISP content filters. For some strange reason, a particular website broke when viewed at home (with a "kids-safe" account), even though this same page worked fine at work. It turned out the javascript code was being filtered and 'TrashItem = 10' was being transformed into 'Tracrapem = 10'. ;-)

I heard that story a long time back, but I still don't like the idea of automatic filters....
