A few years back cloaking in SEO world was understood to be the process of serving different content depending on the IP address of the visitor(not to be confused with geolocation), with the explicit goal of showing keyword optimized page to search engines and the regular user getting a more user friendly page. In my book, this is very similar to what Expert Sex Change does. Come referred by Google you get a nice answer at the bottom, come "clean" and you've got to pay for the answer. Very evil. If you are a big guy (one infamous case was BMW Germany) you can do it, get caught and then recover from Google ban within a week. If you are a small site and get caught don't expect to do so.
