问文章的URL上有大量404个错误

EN

我检查了服务器日志，发现了大量的404个错误。例如，这篇文章的https://historycollection.com/10-little-known-facts-abou-axis-prisoners-of-war-in-world-war-ii/有大约404URL，因为在URL文本中添加了类似于/-&e=MOAT的内容。

URL示例：https://historycollection.com/10-little-known-facts-abou-axis-prisoners-of-war-in-world-war-ii/-&e=MOAT.load

https://historycollection.com/16-horrifying-historical-locations-where-people-continue-to-live-in-the-united-states/4/-&e=MOAT.measurable

https://historycollection.com/10-little-known-facts-abou-axis-prisoners-of-war-in-world-war-ii/-&e=MOAT.viewable&tv=1

他们中的大多数都有像这样的推荐人https://historycollection.com/16-horrifying-historical-locations-where-people-continue-to-live-in-the-united-states/?utm_source=Facebook&utm_medium=Ads&utm_campaign=16-horrifying-historical-locations-where-people-continue-to-live-in-the-united-states-Automatic

以及像这样的用户代理：

有人知道这是怎么回事吗？

谢谢,
