And here's a site that uses different methods for obfuscating the text in the image: http://www.geektools.com/whois.php If you've ever trained any OCR software, you can immediately identify why this is going to be hard for most basic OCR algorithms to process, since there are no discontinuities to identify the breaks between letters. -- David W.
