I hesitated what to take `List` or `Set`. `Set` because order is not
important here, `List` because `blacklist` is common used name, and `List` is
more appropriate for the value which has the `list` word in its name. I don't
see any reasons for `Seq` but if you believe it is important to have `Seq`
instead of `List` here I will replace it.
