Public notes are an issue in keeping the site reputable. We need to decide on the level of moderation we want for them:
A) Only search for common bad words, spam etc, and block those. Otherwise, auto-approve public notes or B) Manually approve public notes, but hide this fact from the user by having the note be visible to only them until approved
Not sure which one will be most ideal, but we can't have the front page be full of spam or explicit content.
