Retype security code before submitting a comment

James Seng provides another – he was the guy that implemented the bayesian filter too – MT plugin to prevent comment spams. The script displays an image with a security code and demands the user to reenter a security code manually before allowing posting to go through. You should make the text on the image as legible as possible to give people with seeing disabilites a chance but it should have a good variation to prevent bots from OCR-reading the information.
