German jurisdication has a tendencey to regulate everything. Therefore, German websites tend to disclaim everything they present. See e.g.
Here are our disclaimers:
We create content which is about astrophysics and not about illegal activities. In case we were absent minded and created illegal documents we will remove them when notified.
We link to other web sites. This is the world wide web after all. The links are intended to be useful and meaningful. Obviously, we cannot control the content on the linked sites. In case we were absent minded and created links to web sites with illegal content we will remove them when notified. We even check from time to time.
The content of this site is copyrighted. Like everything that is created. In case the content is not created by us, we use content that has a license allowing us to use it.
