I just searched for it and your wiki doesn’t exist, so that most likely means that your wiki got closed. Here are some possible reasons why fandom staff could’ve closed it:

If you want the official reason for why it was closed or if you want to appeal the closure, you would need to use the contact form . You can read the closed wikis policy for more information

Another couple more questions. Wouldn't closed wikis still show up on my User Activity page? And shouldn't there be some kind of notification if a wiki I created gets closed?

Sometimes closed wikis will still appear on the UserActivity page, but I think it depends on how long ago they got closed. I think they would only appear if they were closed rather recently

And no, Fandom usually doesn’t send notifications or alert you when closing your wikis. As it says in the Terms of Use, “You understand and agree that others may, but are not obligated to, edit, delete or remove (without notice) any content from the Services, for any reason or no reason.”

Hm. My best guess for why it was closed was the "little to no content" reason. I did have several pages, and all of them were pretty detailed, but maybe it wasn't enough for Fandom. I have seen significantly emptier and more inactive wikis though.

As for other reasons it could have been deleted, I'm really not sure? Really a stretch, but the closest things I can think of are "misinformation" (lots of the ghost photos were fake of course, but I made that pretty clear, I used the words "claimed to be" a lot and never outright said that a ghost photo was legitimate) or "personal information" (If I could find it, I put the real name of people in the photograph. They were always public info though, usually posted by the photographer themself). I don't think it was anywhere close to a duplicate of any other wiki, but maybe the automatic matching tool thought so. Might try to see the official closure reason and/or appeal it.

I just thought of a few other possible reasons the wiki was closed, I feel like these are more likely:

The first is that wikis that are used primarily for images are not allowed, maybe it fell under that category? I would disagree with that, because even though the photos were the focus of the wiki it wasn't just a collection of images. There was a lot of description, history, etc. about each image.

The second, probably more likely, is that some of the photos were copyrighted. Wikipedia does have articles about copyrighted photos, but is able to use them because the photos were the focus of the article and there is no other image that could be used as a replacement. I guess I probably didn't specify that and the wiki got closed.

May I ask, what is spirit photography?

If the Wiki was closed over a month ago, then unfortunately you cannot appeal the closure. When a Wiki is closed you get 30 days in which you can appeal, if successful the Wiki gets re-opened but if not then you have but 30 days to download only the text content of the Wiki (Image & Video Files are not included in content downloads unfortunately) before everything is deleted from the Fandom Database.

That's really cool! Its kinda weird how they deleted your wiki tho.
