Also many reCAPTCHAs are being bypassed, it still work against many robots, although newer robots use Artificial Intelligence and they are quickly able to bypass most of the reCAPTCHAs.

At some point, the main reason for the bypass was the fact that some people were getting paid to resolve those reCAPTCHAs. In other words, some people were offered the job to do just that! They go to a computer, resolve many reCAPTCHAs and get paid something like 2 cents per successful resolutions. The result is that websites with reCAPTCHAs still receive a lot of spam!

In 2017, it looks like such ...

struct swf_metadata {
	swf_tag			f_tag;		/* 77 */
	string			f_metadata;
};

The Metadata tag is used to describe the SWF movie in a robot readable form. It will be used by search engines to index your Flash movies.

The f_metadata string is an XML buffer defined using the RDF definition compliant with the XMP specification. You can find more information on the W3C and other websites:

Note that this description can describe everything, from the entire movie to each single line of code in your action scripts.

The string must be UTF-8 encoded.
