A suggestion.
Perhaps you can kind of give your script a little AI. It might be a little burdening on the script, but maybe an idea for you, or anyone else who wants to try, is to document every character that is used as a substitute for every letter of the alphabet.
Such as....
s={"s","$"};
h={"h","|-|"};
m={"m","/\/\","|\/|"};
t={"t","+","7"};
and have the check use it as a reference for letters, and if any of those letters match one of the letters above, and end up translating into a curse word, censor it.
If that makes sense.
