Many immigrants lived in the Xiongnu pasturelands, but at first they did not mix with the Xiongnu. To be a Xiongnu, one had to be a member of a clan, born of Xiongnu parents. The newcomers were well off, but were outsiders, and could marry only among themselves, not the Xiongnu. Only later did they intermix, increase in numbers, even created a state that existed from 318 to 350 AD.
Xenu
On December 24, 1994, the Xenu story was published on the Internet for the first time in a posting to the Usenet newsgroup alt.religion.scientology, through an anonymous remailer. This led to an online battle between Church of Scientology lawyers and detractors. Older versions of OT levels I to VII were brought as exhibits attached to a declaration by Steven Fishman on April 9, 1993, as part of "Church of Scientology International v. Fishman and Geertz". The text of this declaration and its exhibits, collectively known as the Fishman Affidavit, were posted to the Internet newsgroup alt.religion.scientology in August 1995 by Arnie Lerma and on the World Wide Web by David S. Touretzky. This was a subject of great controversy and legal battles for several years. There was a copyright raid on Lerma's house (leading to massive mirroring of the documents) and a suit against Dutch writer Karin Spaink—the Church bringing suit on copyright violation grounds for reproducing the source material, and also claiming rewordings would reveal a trade secret.
