The email CAPTCHA should be bot-proof now. Maybe it was already bot-proof, but the latest changes I've made should require AI on a par with human intelligence to solve, or at least something far more sophisticated than I expect to be searching our websites for email addresses. It now uses a variety of randomly generated colors within a range that is dark enough for a white background. After everything gets written, the colors get scattered, such that neighboring pixels rarely have the same color, but not so much that humans will even take much notice of the differences. Finally, it is rendered as a JPG, which is a lossy format. The bottom line is that your email addresses are now safe from bots on this site. If you still want to keep your email address private, all you will gain is privacy from other humans. Privacy from bots is taken care of.
