There's a hidden form in the navbar, over there on the right, that is title "Your Website" and contains a textbox and submit button. This form is invisible to most browsers, but if you disable CSS or access the site through other means, it will be visible.
If you see this form, do not put anything in it. Your submission will be marked as spam and you may be banned from accessing the site. My goal is to trap automated bots and see it affects the graph over there on the right. Right now, you'll see spam is at 66%, which is just from me testing things out. We'll have to see how this works over the next few days, and I'll enable IP-level banning upon the submission of spam if it works.
