告诉HN：YouTube历史记录设置的隐私影响
作为用户观看者（而非频道拥有者），我已将YouTube历史记录设置为仅保留最多3个月，然后自动删除。今天我检查发现，这个设置仅适用于用户的视频观看历史。
要手动删除您在YouTube上的点赞和点踩，您需要访问 https://myactivity.google.com/page?page=youtube_comment_likes。
要删除评论，请访问 https://myactivity.google.com/page?hl=en&utm_medium=web&utm_source=youtube&page=youtube_comments。
