nsfw或擦边图片极其容易被tx吞，若增加像素点微量修改则可以有效避免。

As Koishi no longer officially support onebot or red, we are not going to support this platform-specific feature, but it can still be implemented by other plugins:

ctx.before('send', (_, options) => {
  if (options?.session?.argv?.command?.name === 'booru') {
    session.elements = h.traverse(session.content, {
      image(val) {
        return change(val) // do some changes for the image
      },
    })
  }
})
