I was checking on an old project of mine, a wiki for the 2002 puzzle game Enigma. When I tried to visit a page, it was stated that the wiki was closed. I was offered no warnings, no notifications that this had occured, and no reason as to why it happened. Could somebody explain what is going on? Should I contact FANDOM directly?
Fandom periodically goes through and removes small inactive wikis. They also remove wikis if there are serious policy violations or no one around to correct policy violations. In addition, UCP wikis that duplicate topics are removed. You will need to contact Fandom directly to find out why your wiki was removed. Depending on the reason, you may be able to request that they reopen it.
The last edit by GreenGalaxy was October 2017. If it closed for the recent big site hygiene move, there's probably still a backup. If it was snapped up by an earlier round, doubtful.
Pruning old and abandoned wikis is a great way of fighting cruft - tons of personal Roblox or fanon wikis - there's unfortunately occasionally a small wiki among them that has unique content that someone might find useful, years later.
