The Scientology crime syndicate has at most some 20,000 surviving customers world wide thanks to the advent of the wide dissemination of information about the enterprise that is possible using the Internet, including detailed information about the syndicate's gross human rights crimes and abuses as well as their massive financial frauds and scams which, despite the small number of customers, reaches across numerous countries.
Of particular notice is Scientology's quack medical frauds they call "NarCONon" which tricks people in to thinking that they are giving tens of thousands of dollars to actual drug treatment and rehabilitation facilities when in fact they are handing their money to Scientology and using Scientology's bizarre "Purification Rundown" quack medical frauds to literally scrape invisible murdered space alien fragments off of themselves, aliens which the enterprise calls "Body Thetans."
Thankfully no United States entity considers the enterprise to be a religion, it is classified as a "tax exempt charity" in the United States which, on its face, is also fraudulent.
If people want actual information about Scientology, the Xenu.Net web site gives good coverage of what these crooks sell to the rubes, marks, and suckers who don't bother to find out what they're buying when they hand their money to Scientology.
Also the "Underground Bunker" run by award-winning journalist Tony Ortega is a wealth of information about what Scientology actually is, what it does, the endless criminal and civil cases instigated against the criminal enterprise, as well as highly detailed information about Scientology murders and associated fatalities, often committed under Scientology's "NarCONon" banner.
