Our private team of gamers has a small gaming community. In order to increase our reach of people and to let our community grow, we do provide some users with free Minecraft servers, as well as hosting space for files on our servers.
As trusting people in the internet is a difficult topic, we want to be sure that if we do provide them with our services (Minecraft server, file hosting for server files and ressources, community forums), we are not responsible for the contents that the service user hosts on our servers.
It's not that we don't constantly check what's going on on our servers but we want to be on the lawful side and make sure we cannot be sued for helping others host their Minecraft servers and files on our servers.
Is it valid to let every upcoming server administrator that we donate some "hardware" sign a document that states that he is solely responsible for his server as well as he has to comply German laws and the Minecraft EULA?
This document will also include that it is prohibited to host illegal files (files one has no rights for, adult material, hate-motivated etc.).
We will still continue constantly monitoring what is going on and log every action on our sites.
Our servers are located in Germany so if I am not wrong, German right apply.
Is there any basis we can build such a document on, is such a document even allowed, what is such a document called (disclaimer?)?
