A thread I started over at SEW forums named How Do I Spot Cloaked Sites? began to take on a civilized and professional discussion on detecting cloaking. The thread did not, and should not, go into the realm of ethics, but rather it will remain on the 'how to".
Half way into the thread, there was need for someone who would be considered an expert in cloaking. Danny Sullivan was able to encourage fantomaster (Ralph Tegtmeier), one of the most well known experts in the cloaking field, to participate in the thread. And at post #43, fantomaster joins the thread. He then goes on to post three additional times, post #56, post #68, and post #71.
