Why have most fan-made wikis been shut down?
They are usually duplicates, or have an extremely obscure topic that almost no one is interested in, you could ask staff to provide more info on these kind of wikis
Ok, all the wikis I know of that me and my friends have made have disappeared even one that had been going for over 2 years and it was very active...
As I said earlier, you could ask staff to to give you more information on why those wikis are closed
Ok, should I ping someone to this post or should I wait for them to see it?
No, use the contact form
