Proper filtering is necessarily tedious. There is no way to filter a
last name, a server name, a file name, an IP address, a ZIP code, and a
comment with the same function. Those who try wind up creating a "lowest
common denominator" filtering function, or they confuse filtering with
escaping (as demonstrated by some of the replies).

As a good friend of mine likes to say, you have to get your hands dirty.

Hope that helps.
