Actually they got back to me and confirmed it was due to inactivity. They said I can't get my data back because it was more than 30 days ago, great :D
Thanks for your comments everyone. I sent a request to get the wiki reopened or its contents downloaded. It was definitely inactive and quite small for a while so I assume thats the reason for its shutdown.
The wiki in question was Antisocial.wikia.com, or perhaps fandom.com. It had a lot of important archival information that I'd like back. I don't believe I deleted it, so I assume it was removed by mods. There definitely wasn't anything against the rules.
Thanks!
