Notice due to imprint?

I'm with a Minecraft Server Admin, but I'm not the main admin I'm running the forum, which of course contains the name of the server, the imprint and the privacy policy are under me, something could happen to me if they would now legally protect the name, so if they were going to do anything I could display me etc.

Who is "the" in the subset "if they are now"?

And which name could be legally protected?

And who is the operator, the entrepreneur of the website you work for?
