True they can't, but a bureaucrat can promote them.
In case there are no active bureucrats on the wiki and the admins have the approval of the community, they can request bureaucrat rights via the wiki adoption process.
I gave someone a B-crat Rights and i cant seem to remove them. If i report Fandom about it, they'll end up reporting me for doing something i didnt do.
And no, B-crat doesn't help me agaisnt raids, i never said that. I said incase someone who is a Sysop promoted themselves secretly to B-crat and raided the Wiki due to me cant remove the B-crat.
