Noone was trying to circumvent anything, I simply asked what 4 letter word goes there (as I seriously didn’t think of the 4 letter variant for a sec).
Also, your filter is nonsense. Almost on forum is an adult (or should be, and it’s not like those kids you’re trying to protect are the ones using the most “bad” words is it?). If someone takes random words people write on a forum not even directed at anyone as a personal insult then he should not be on the internet.
