Liabilities for the removal or inhibition of information usage according to general law are unaffected. However, an accountability in this regard is only possible as recently as a concrete violation is known. After infringements of rights became known we will remove the relevant contents immediately.

Liability for links

This website contains links to external websites of third persons which are not under our control. Therefore no responsibility is taken for the foreign contents.

The linked resources have been checked for possible unlawful content at the time the links have been created. No illegal contents could be recognized at the time of linking. A permanent check with regards to contents without concrete evidence is unreasonable. As soon as we get known to violations we will remove relevant links immediately.
