Adobe’s announcement that Google and Yahoo! will be indexing Flash content at a much deeper level was met with all sorts of reactions last week, ranging from praise from the Flash and Flex communities to utter shock and horror from some HTML fundamentalists expressing fear that the end was nigh.

Well, it appears that Google has already started using this new indexing system and some Flash developers are not happy by how much it is revealing about their applications.

Peter Elst, a prominent Flash developer (diclaimer: and member of the Flash Pack on Pistach.io, of which I am a partner), just Twittered the following:

oh no, SWF indexing seems to do just as I feared — already noticed Google was picking up my test Flash SEO swf but its now exposing URL’s

And posted his concerns on his blog, wherein he quotes Ryan Stewart from Adobe on what exactly is getting indexed:

… it will move through the states of your application, get data from the server when your application normally would, and it will capture all of the text and data that you’ve got inside of your Flash-based application.

Peter goes on to state why this could be dangerous:

The concern I have here is that URL requests to the backend will get indexed, those URLs getting exposed in search queries or spider bots hitting those URLs could cause issues. Its not like in HTML content where the search engines can ignore form submit URLs, there is no such context in a HTTPService or URLRequest.
