Hello,
Is there a way to disable or delete automatically generating about page whenever creating a new category?
No, this is required.
You can unlist it. Click the wrench at the upper right.
Yes, I am doing this everytime. Thank you for the response. 
For a site with hundreds of categories I wrote a script that did it to all of them at once.
Can you share that script?
出于好奇，为什么这个页面是必需的？
可以像本主题中的另外两个人一样取消列出该页面，但它仍然出现在 API 中，尽管并未被使用。
那么，将其设计为可删除不是更有意义吗？
类别描述就存储在那里。
在类别最初构思时，情况并非如此。大多数网站都希望能够置顶类别描述。这很少成为问题，所以不，这并不合理。
