This Web site contains links to Web sites from third parties (“external links”). The liability for these Web sites is carried by the individual operator. With the first linking to these Web sites, the supplier checked the foreign content for any breach of law. At that point, no breach of law was apparent. The supplier has absolutely no influence on the current and future structuring and the content of the linked sites. Placing external links does not mean that the supplier makes the content behind the reference or link his own. A continuous control of these external links without concrete indication of a breach of law is for the supplier beyond reasonable. With knowledge of a breach of law, however, this sort of external link will be promptly removed.
