So, on the Gacha Life fanon wiki, I found a really harmful user. That user is removing content from both pages and user profiles. That user has edited so many pages and even after I reverted the edit, in over half a hour they did it again. The admin is not an option because I wanted to message them but it says that the user is either "globally disabled by fandom or by user choice". And that is the only admin.
I just don't want that user to harm the wiki even more. And also, on the admin's message wall, that user said that they want to take over the wiki. Well, let me specify. That user is called NewyDewyCewy (apparently, there are two of them, this is the second: ARC38ViceAdministrator).
Also, this is the screenshot from "wanting to take over the wiki"
And this is the screenshot I made when I was reverting the page.
So these are the people I would like to get blocked.
