Frankly im finding on a number of sites that google is doing just about what it likes.
Not just ignoring no index, no follow robot tags etc but also its now reading files within java script etc.
Meanwhile googles attitude is kind of "Well if you dont want us to crawl your site we will take it out the index"
Bottom line is imo that you will have to either put up with the abuse of google ransacking everything on your pages OR get your site removed from its search.
Not much of an option!
