Scam.com quite often is used by people to blow of steam about a company, the real issue is it's not really referred by anyone as there are so many comments being added to it all the time.
Here is what it says on scam.com website about complaints:
This website assumes no responsibility for comments or content based on these US Court rulings:
Barrett v. Rosenthal:Websites assume no responsibility for comments or content provided by third parties as provided by ample case law including the recent California decision in Barrett v. Rosenthal. You can read the case here
Federal Court Reaffirms Immunity of Bloggers and Forums from Suits Brought Against Commenters Section 230 of the Communications Decency Act provides that "[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," and that "[n]o cause of action may be brought and no liability may be imposed under any State or local law that is inconsistent with this section." A recent decision of the First Circuit has reaffirmed the broad protection this statute provides to bloggers and message board administrators.
In Universal Communication Systems v. Lycos, a company who had allegedly been victimized by defamatory statements on a message board regarding the value of its stock sued Lycos, which operated the board. The message board allowed users to post comments with minimal moderation, and no one from Lycos was responsible for the allegedly defamatory statements.
Examining the impact of Sec. 230 on this case, the court noted that "Congress intended that, within broad limits, message board operators would not be held responsible for the postings made by others on that board," adding that allowing bloggers and message board operators to be sued for the statements of commenters on their sites would have an "obvious chilling effect" on speech. Accordingly, the court dismissed the complaint against Lycos. News Source
I am not sure how this would stand in a European court I guess only time will tell.
