This wiki is unfixable in its current state, and it probably won't change anytime soon from what it is now. So I am making a solution that I feel is right.
The flaw of this wiki is that nonsense and serious projects co-exist. People who wish to create serious projects have to have their project be among spam and memes, while people who wish to post nonsense have to be among people who want to build worlds without any silliness. That is ultimately what caused the downfall of this wiki -- the entire concept was flawed from the beginning.
My solution is this. There will be two wikis -- this one being a less serious subsidiary to a larger wiki, a larger wiki where only actual projects are allowed. Any spam/nonsense will be deleted from that new wiki.
Nothing will change on this wiki. Everything will remain the same and nothing is being altered or deleted here. This wiki will still be moderated and the concept will remain the same, but focus will be on the new wiki rather than this one.
I suggest that anyone who wants to create content in a fresh field to move your projects to the new wiki. This can easily be done using the Import and Export features, so please message me if you want me to move your project (preferrably multiple-page projects).
For now, this new wiki will not be revealed and only certain individuals will have access to it, but I will reveal the link soon. If you want access to the new wiki, please message me. Thank you.
