The dreaded comments CAPTCHA has returned to JZ:TOL. I dislike these, but the volume of comment SPAM has increased dramatically since this blog has been linked by several higher traffic blogs. There are also several common Google searches that seem to land here. I’ve been selectively banning IP addresses (virtually everything from China) for several months, which has helped, but it wasn’t enough. Hence the reintroduction of the anti-spam code requirement to post a comment. Hopefully, the balance between convenience for the commentators and sanity for the webmaster will be tolerable.
