Talk about click bait....
no one in that awful organization is "employed" to do anything.
they do not have "phone banks" anywhere, even if individual witnesses use their phones to spread their cult
by using the words "employ" and "work " together you imply a relationship you absolutely know dosent exist in this context.
You use the term "preteen" along with "work" and "employ" to further the 'click bait' nature of your post by implying underage sweatshop labor, perhaps even trying to draw some vauge reference or connection to abuse by including the religious knowing full well the charged atmosphere that surrounds children and religion.
As much as i hate the cult sensational and flatly untrue statments, like those made by the tittle of your post, do far more harm than good. There is more than enough to hang the cult on without resorting to untruth.
