Badwords and new threads/posts
 

I need to do the next:

Filter the new messages (thread or posts) with badwords within it's body or title. I don't want to censor them, I need the follow:

- IF the message hasn't bad words then it will reach the board as usual
- ELSE IF the message have a bad word on it, I need that one get to the "pending moderate" list

is there any way to do this? I've searched quite a lot on google, but there's two options:
a) I don't know how to look for it (wrong search terms) :P
b) It doesn't exists hehe
