Crud. I’ve waited too long and I can’t edit the post.
Alright. I’ve figured it out. I added a text widget (even though I said I didn’t want to) with no title and the code similar to the one I included above.
Now when I view the site, the widget doesn’t appear (as I’ve entered no title) and because the code is hidden, it doesn’t appear either. I’ve verified that it is, in fact, there by viewing the source code.
But you still ought to all join the Project Honeypot…
