Are you responsible for any webpages? Including forms? Then take a look at this utility: Web Form SPAM Protection. It lets you protect your on-line forms from the risk of being scanned by spam robots.
The program can load websites from your local hard drive (or from an on-line URL), and convert the pieces of HTML code corresponding to the forms to encrypted Javascript, which is visually the same, but internally can“t be seen by spam robots. You can save the new webpage as a new file, and upload it to a server substituting the original file.
