The White List is replaced with the black list when the user reaches 13 years of birth.

The White List is for people 12 years and younger. They limite what people can say, if any word that are not in the White List is said, it is replaced with #s.

The Black List is what people 13 and up cannot say. (Which is what words are swear words.) BUT, there are a lot of missing swear words missing from it. If someone with a White List sees someone with a Black list say smething that's not a swear word, but not in the White List, only the people with White Lists can't see what the Black Lister said.
