アカウント削除をリクエストしたユーザーで問題が発生しました。アカウント削除前に、ユーザー管理セクションで「すべての投稿を削除」を使用しようとしたところ、アクションを確認した後に Error 500 が表示されました。
今のところ、手動で見つけられた投稿は削除しました。このユーザーは投稿数がかなり少なかったので、問題ありませんでした。しかし、まだこのアカウントの「作成した投稿」が 10 以上と表示されています。そしてもちろん、アカウントを削除できません。また、このユーザーによる投稿はもう表示されません。
/logs で、このイベントに関する 2 つのログエントリを確認しました（私の推測では）。

これらの reviewable_notes と reviewable_notes テーブルは何ですか？モデレーターの「レビュー」キューに関連するものですか？
