You said multiple personas because "nobody would believe all of the statements coming from the same mind". You also said "none of them tell blatant lies", and your personas had topics on the top of the boards for weeks.
I assume all of your personas to be religionists. Although there are a few non-believers with threads that remained at the top of the boards, I would rule them out, because to me, for you to have non-believer profile/s would be a blatant lie.
I think you have at least one persona whose name and/or avatar suggest a Jew or Muslim. There are several persona that fit this and throw out provocative questions, but do not actually make statements that they are of that faith.
I think most of your personas have few if any hubs, and little if any info on their profile page. I think some personas have many forum posts, but others are hit and run. They post a provocative thread, then let everyone else create the fireworks, making few additional posts to the thread themselves.
