Why do you need a sandbox wiki? If you are just concerned with learning how to add basic content (i.e. won't need any special rights), then you can use a dedicated test wiki such as this one.

It isn't clear to me what the topic of the non-test wiki you linked to is. Either way, duplicating the topic of an existing wiki is one of the more common ways to get your wiki closed. Between the content that is on the non-test wiki and your comment, it sounds like the content you intend to post is real information about real people other than public figures. Please note that this is strongly discouraged in the Terms of Use (via the "Living People" section of the Community Creation Policy) which you agree to by using Fandom's services.

All that said, HumansCanWinElves is correct. Only staff can tell you why your wiki was closed.
