There actually is a tactic used by the "Church" of
$cientology that goes by this name. It involves using
the Court system to silence any of their critics. In
doing so, they are violating others' 1st Amendment rights.
This organization, described as crackpots, idiotic, and
other similar epithets is by definition a religious cult,
and one of the accusations levelled at them is that they
exert mind control over their participants. On the Web,
they've used SLAPP lawsuits and now the DMCA to censor
their critics, and in an extreme case of what can only
be called body snatching, they shut down and took over
the Cult Awareness Network's website - it is now manned
by $cientologists. Yet another accusation directed at
them is that they are scamming people out of their
money. In some countries, most notably Germany, the group's
members have been arrested and the practice outright
banned. The A&E Cable TV network did a 2 hour investigative
report on $cientology: a lot of this information came from
that investigation, with the help of ex-$cientologists
and critics alike. The A&E program was called Investigative
Reports: Inside Scientology, and the video can be ordered
from their
website(for anyone who is interested).
