英文中，用refute the rumor来表示“辟谣”。

Why didn't he refute the rumor？

他为啥不辟谣？

She finally came up and refuted the rumors about her family.

她最终还是站出来辟谣了关于她家庭的谣言。

那么，“微博辟谣”，又应该怎么表达呢？

请看一段英文报道↓↓↓

Sina said it has created a separate channel dubbed “Weibo Refutes Rumors” to spread denials of false information. It announced an email address for users to send reports of possible falsehoods.

新浪网表示已创建单独的“微博辟谣”频道，告知用户哪些是虚假信息。新浪还专设了举报邮箱，供用户举报疑似虚假消息。

文中的Weibo Refutes Rumors就是指“微博辟谣”，也可以称为rumor refutal。

谣言散布群体常称为rumor mill（谣言工厂，流言簿）。

Rumor可以直接作动词，如：

It is rumored that she has committed suicide.

据传闻，她已自杀身亡。
