We have had several comments lately about problems with the “captcha” function on comments. As you might imagine, UD is inundated with spam, and the captcha function is designed to prevent the spammers from accessing the combox.
We have decided, however, to ratchet back on the captcha. Now, you will need to fill in the captcha only when you log in to your user ID. You will not need to fill it in to post comments.
We will try this for a while. We worry that advanced spammers will take advantage of it, and if that happens we might have to change course. But for now we will see how this works.
