I just added on few my sites new section in terms and conditions. New rules prohibit any automatic scanning/indexing of website. Privilege for accessing our website given only for human visitors. Search engine bot will able to index website if send us at least 10 visitors per day. Otherwise that permission will revoked. It not matter what googlebot not able to read text (however Matt Cutts tell what it very smart). My website is my property and only me can define terms of accessing of my site. Googlebot NOT HAVE default accessing permission to my site. So - later it can lead to huge process. My recommendation to all webmasters add similar section to their terms, later we may be will able to using it. Lets google understand what websites is NOT THEIR PROPERTY and them also need to do something if them want to index the web!
