Also the community could ask Fandom to check if the bureaucrat promoting the other against the community desire is not controlling both accounts. I've seen cases where an admin uses a sock puppet account to bully members of the community. Then, when the community demands for disciplinary actions, the admin in their primary account will seem to not listen, pretend not to understand the seriousness of the issue, and/or apply very soft punishments to their secondary account.
But sometimes they're just two people with a disordered affection towards each other, which ends up creating problems to the community.
