Who enforces the beginner tag? Will people be offended by the beginner tag, too? Just seems like it's the same problem but with a different name.
Without the tag "enforcement" means censoring a co-user and the problem manifests as "who can wield this authority fairly and justly against their co-users"? With the tag enforcement means who can triage new posts to tag them appropriately when a co-user does not. They're not the same problems and I think objectively this is a better problem to have.
