Cyber-critics, free speech and online anonymous web postings have become a combustable combination. The result is cyberSLAPP law suits, which seek to force ISPs to reveal the names of those who have posted anonymous statements critical of high profile individuals.
An example of just such a case involves a Pennsylvania judge and a now defunct web site, which I discussed in my posting, Judge v. Anonymous Web Critic.
To monitor cases and information on this issue, I recommend cyberSLAPP.org, founded in July 2002, and “sponsored by a coalition of civil liberties and privacy groups.” Here you will find links to full-text of cyberSLAPP briefs and opinions.
