Personally, I addressed the problem with CSS: .CategorySelect.editMode > .toolbar:before { display: block; content: "This is not a search box. Do not add nonexisting categories."; float: left; color: red; line-height: 1.7em; } After adding that, the number of anons adding nonsense categories has decreased, so a similar warning might also work for you. This will be useful - thanks for sharing.
