If you are going to make it a site that elaborates upon your personal experience with SuperiorPapers.com, and you have evidence to support your statements, that's legally safe. You can then allow people to communicate their own proof-based experiences with SuperiorPapers.com in a forum. What I'm telling you is that you will run into serious problems with OTHER companies against which you do not have such evidence, whether or not you personally make the posts. Once you are presented with evidence that a post is untrue or inaccurate, I believe precedent dictates that you are thereafter legally responsible for damages caused to the libeled company if you do not remove the post.

On a personal level, I must add that taking "essayscams.com" (and posting about it here in essayscam.org) is in very bad taste.

The CDA is part of our federal laws. An excellent Wikipedia article discussing the history of the law can be found here.

In short, the CDA provides that when a user writes and posts material on a website such as Ripoff Report, the site itself cannot, in most cases, be held legally responsible for the posted material. Specifically, 47 U.S.C. § 230(c)(1) states, "No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider." Because the reports on Ripoff Report are authored by users of the site, we cannot be legally regarded as the "publisher or speaker" of the reports contained here, and hence we are not liable for reports even if they contain false or inaccurate information.

In most cases. In ripoff case, Court found that out of 110 complaints posted thereat, only 11 were from true complainants. The rest were made up by ripoff staff. This established a designed plan--something like a 'conspiracy' for the accomplishment of illegal ends. There was RICO.
Other states penalize libel as a criminal offense--while others consider defamation as tort. There is a plethora of jurisprudence where parties were found guilty of defamation and libel.

Media laws is a complex field: issues of jurisdiction,liabilities of parties, i.e. distributorship, ISP, posters, nature of offenses etc usually entails in depth research from authoritative materials (such as the confluence of pertinent laws and court cases)and experience in the field.

Issue of jurisdiction--assuming arguendo that complaining party is not within the the 'jurisdiction' you were alluding to--it can still be filed anywhere--where the site was accessed and the defamatory contents read--as this is deemed 'publication.' (This includes hyperlinking).

There really is nothing to worry about if you are in good faith.
Establishing a site for the purpose of exposing fraud is noble even if you were a victim. Try reading the first (web) page of this forum--obviously, as stated --they set up this site because they too were victims.

What transpires after setting up is a new ball game.
Bye and goodluck to you!
