阿基斯梅特 is an anti-spam plugin that comes pre-installed with WordPress. It filters all WordPress comments on your website through their anti-spam database and catches the most common types of spam comments.
Simply go to 设置 » 讨论, under ‘Other comment settings’ you will see the option ‘Automatically close comments on articles older than’. Check the box next to this option and enter the number of days you want comments to be displayed on a post.
WordPress will now automatically close comments on posts older than the number of days you defined for this option. If you need, you can 覆盖 WordPress 中的评论截止日期 for individual posts where you would like comments to remain open.
In case you feel that you don’t need comments on your WordPress site, or comment moderation goes out of your hands, remember that you can always switch off comments in WordPress. All you have to do is go to 设置 » 讨论 and uncheck the box next to “允许人们对新文章发表评论”.
