As I said, the word would be separated by non characters... so just "sex"
wouldn't trip the censor, but if you did a search for things like " sex "
and " sex." and actually found something, then it would be something to
look into :)... Besides I never said the filter would block the word sex,
and that would be an especially bad idea because sex can mean either
sexual intercourse (which isnt necessarily pornography) or gender, which
shouldnt be blocked either... What will most likely be blocked are words
that most people consider offensive... And I'm sure you can think of a
few... :)
Well, thanks everyone to those who responded... most gave something
interesting to think about... However, it looks like I'm gonna have to do
this by myself, so I've started messing up things like packet.c and
trying to figure out where all the data flows and how to scan it... I see
many kernel malfunctions in my future :)... But if anyone wants to point
me in the right direction occasionally, or maybe even help me write some
parts of it, I would appreciatte it alot (considering I just moved to C,
its gonna be tough... but I'm gonna do it anyway:)
Later,
