"I don't know" 💔
My guess? People just wanted to make some changes to some Wiki pages and maybe a lot of YouTubers were promoting this Wiki, now probably not as much anymore, and popularity and hype for this Wiki died down.
I can't check editing, since my activity on the editing side is little to none.
Nothing can stay big forever, even if it is a Wiki about a large community and huge potential. 2024 could've been the best year, maybe not, but I do think that 2024 was better than 2025.
