When searching for various programming information on Google, many times it will give results from experts-exchange.com on the first page. When I click it I'm told "sorry, you gotta pay if you want to see it", so I just view Google's cached version instead (where I can view the text I was looking for). Now correct me if I'm wrong, but isn't this cloaking, a Google no-no? More specifically, how does one go about legitimately cloaking content in this manner for paid-subscription web sites?
