Forums are an "especially dangerous feature" of websites, according to a ruling published last week by a Hamburg district court. Heise Online says it has been found liable for content that appeared on forums, despite the content being removed on request.

Advert: Infosecurity Europe, 25-27 April 2006, Olympia, LondonHeise ran an article that criticised the business practices of a Munich company called Universal Boards. Some participants in its accompanying forum appear to have encouraged as many people as possible to download a file as often as possible from Universal Boards to disrupt its servers. The company sent a warning to Heise to refrain from "actively disseminating" these reader comments.

Universal Boards went to court and obtained what Heise called a temporary restraining order – presumably to prevent similar postings in future. Heise says the court did not believe its argument that pre-vetting more than 200,000 comments per month would be an unreasonable burden.

Heise plans to appeal the ruling. Its legal adviser, Joerh Heirdich, said: "Moderation of user comments would mean the end of the fledgling forum culture in Germany."

OUT-LAW has not had sight of the ruling, but the general guidance for operators in the UK is to decide whether to moderate or not moderate a forum. Either approach is acceptable but each carries some risk. With a moderated forum, the moderator can become liable for content that appears online. With an unmoderated forum, there must be a facility for requesting the removal of content and such requests must be dealt with promptly. Similar rules should apply in Germany since both countries have implemented the EU's E-commerce Directive which contains these protections.
