Keyword system on adult websites

I would like to know if anyone knows how to make this keyword system on adult sites. I noticed that many are using it to index thousands of keywords in a mass organic way.

As I understand some use Script to generate these keywords in bulk. Others use some plugin in wordpress, but I can't find anywhere to buy this system.

If anyone knows how to make or knows any company that sells this type of scheme.

Example sites: redwap. me and hdvideosporn. net
