Scientology's not in the top five total, but on a per-capita basis it may be winning for number of people enslaved, although it's very difficult to get solid numbers. There are under 50,000 scientologists, and their "Sea Org" members who signed "billion year contracts" may have had as many as 5,000 people, so that's perhaps one slave for every 10 scientologists. But, again, reliable numbers are hard, so that estimate could easily be off by an order of magnitude.
