They are probably counting clicks to the link requesting a study, many of which are purely accidental. A few probably misclicked, and many probably just clicked because they were curious. Anyone with half a brain could "study" by typing the organization into their search engine and reading the variety of web sites that come up. If anyone has a whole brain, they could "study" by typing "Christianity a lie" into their search engine after completing research on the jokehovian religion, and reading some of the sites they get that way.
Anyone that, despite having free access to the entire web, completes a study and gets baptized through the washtowel site is probably a complete idiot or mentally deranged and not competent to make their own decisions anyways. Do they want to worship Jesus? There are plenty of xian web sites not affiliated with the cat lick church. They want Judaism or Islam? There are also plenty of ways to get into those religions. And, if they wish to worship Satan, there are a few good sites teaching them how to do that properly and openly. As for worshiping one god while pretending they are worshiping another, I don't think they are going to get a whole lot of decent people that way--certainly not when the jokehovians pretend to be pure xian but are in fact more obsessed with spiritual Israel and tying in with Israel than anything else.
