This guy claims that is phony, and that it’s just a way to launch time-delay pop-up ads. One reason: “[T]he PsychoEx domain name was registered on February 15, after the first of the messages but well before the final message. It seems likely, therefore, that the plan for the site was drawn up before the messages were received, which again suggests a hoax.” (A few days ago, I got a pop-up that I coudn’t trace. Could be the culprit?)Link
