No, because the Active Text tool replaces the final txt that is displayed in the post in real time. Unlike the censor (word/phrase) replacement, which replaces the text first, before doing any else to the user input.
censor recommends that you rebuild the posts/private messages/sigs after making changes to your list.
Active Text does just as its name suggests, it actively changes the text on the fly. in real time as the post page is being created.
