好发现 @bksubhuti 👍 将通过以下链接修复
>
>
> When a moderator disagreed with a flag on a hidden post, \`Post#unhide!\` re-ran \`…PostValidator\` against \`acting\_user\`, which defaults to the post's author. If the author had since lost trust (e.g. demoted to TL0) and the post's content exceeded new-user limits (embedded media, links, mentions, host spam), the update failed with \`ActiveRecord::RecordInvalid\` and the post stayed hidden.
>
> Every other internal caller of \`Post#unhide!\` already sets \`acting\_user\` to whoever is performing the action so validations run against the staff member, not the original poster — \`PostsController#unhide\`, \`ReviewablePost#perform\_approve\_and\_unhide\`, \`ReviewableActionBuilder#perform\_unhide\_post\`, and \`PostActionDestroyer\`. \`ReviewableFlaggedPost#perform\_disagree\` was the lone exception.
>
> Set \`post.acting\_user = performed\_by\` before calling \`post.unhide!\` to follow the established convention. The post content and ownership are untouched; this only affects which user the validator inspects during the update.
