You can contact Fandom staff (Special:Contact) and ask them why was it deleted and if there is an option that they'll restore it or at least give you the contents of it.

Not that my opinion changes anything, but inactivity for a long time is definitely a reasonable reason. Fandom is not a website hosting service (which you would have paying to if you wanted to have), it's a commercial company which holds websites as their bussiness.
