The theme one of my sites is using does not have a comments form nor is there any HTML markup for comments anywhere within the code.
So, how am I receiving spam comments?
All the spam is caught by akismet and I can change the Discussion Settings so only registered and logged-in users can comment (and a few other settings) -- so the question is not "HOW to reduce spam" but how do spammers (bots or humans) submit spam without a form?
