a message sent to a computer when a link has been created to a person's blog post from another website, so that they can create a link to that other website

A pingback is a special type of comment that is created when you link to another blog post. “自动引用通知”是一种特殊类型的评注，当你链接到另一篇博客文章时就会自动创建。

I turned off "allow trackbacks and pingbacks". 我关闭了 "允许参照和自动引用通知"功能。
