@Seanbluekiller Was your Wiki a Chat Wiki by any chance, as chat Wikis are not allowed on Fandom and they will be closed by Fandom Staff? Additionally if your Wiki was a "Private" Wiki wherein only you and a select group of people such as admins & bureaucrats etc could edit due to protecting the pages, then it would also have been closed as Fandom do not support Private Wikis, if you wish to make a Private Wiki, you can use Mirazahe.
Before you make anymore Wikis, you could potentially first take the time to read the Community Creation Policy as your Wiki could have also been closed down due to breaching this policy (Link to Community Creation Policy - https://www.fandom.com/community-creation-policy)
However, if you want to discuss why your Wiki may have been closed with Fandom Staff then feel free to use the link provided below in order to do so:
