As an organization though I tend to give a fair degree of credence to the horror stories, though the really awful stuff seems to be the experience of a minimal number participants.

The really awful stuff is the experience of those with less money
to contribute, those who have displeased certain higher ups, and those who write or speak negatively about them publically. Shit, they're literally selling people salvation, making them work like crazy and paying them very little. You ever watch Malcolm In The Middle? You know when Frances gets to that logging camp and LaVernia works them to the bone and dude gets like a $7 check? Yeah, that shit's a real part of scientology. Not for everyone, but for many, and they make Comcast look like customer service rock stars in contrast when it comes to trying to leave.

They follow people, harass them, and sue like crazy. They’ve infiltrated multiple governments. People who have left report being followed and harassed, along with being punished by being denied access to family members. There’s a pretty deep rabbit hole with scientology and the awful stuff really isn’t relegated to a small handful of people.

Shit, their leaders own wife- who was also highly ranked in the organization- was most likely relegated to a work camp. This is unconfirmed but she’s been “missing” since 07 and their history leads to either that or murder as the likeliest conclusions. One guy climbed a bladed fence to escape.

As with anything, people have different experiences, but there's enough documented information to conclude that scientology definitely has more than a minimal amount of people who have experienced the ugly side of the organization.
