all that is there is this reply:
There's a news report in German here:
Two researchers: Florian Heinz and Martin Kluge discovered that the
WHOIS server for some top level domains will only provide the contact
e-mail address as an image.
Comodo was using OCR to extract the e-mail address so it could send a
verification e-mail to the domain. Their OCR was faulty, and the
researchers tricked it into sending the e-mail to a different domain.
Comodo has made very negative comments about these domain registrars.
