We never said that you can't ban someone without approval. It's just that you can't ban supposed duplicate accounts. Duplicate accounts will not be enforced by mods at all, even if they have proof, unless they break other rules, because the admins have much better tools for detecting and dealing with duplicates, like IP blocking and CheckUser.
