I have a bunch of blog posts, with URLs like these:

  https://mywebsite/1-post-title
  https://mywebsite/2-post-title-second
  https://mywebsite/3-post-title-third
  https://mywebsite/4-etc

For some reason, it tries every combination of numbers, so the requests look like this:

  https://mywebsite/1-post-title/2-post-title-second
  https://mywebsite/1-post-title/3-post-title-third

etc.

Since the blog engine simply discards everything after number (1,2,3...) and just serves the content for blog post #1, #2, #3,... the web server returns a valid page. However, all those pages are the same.

The main problem here is that there is no website page that has such compound links like https://mywebsite/1-post-title/2-post-title-second

So it's clearly some bug in the crawler.

Maybe OpenAI is using AI code for their crawler because it has so dumb bugs you cannot believe any human would write it.

They will make 90000 requests to load my small blog with 300 posts.

Cannot imagine what happens with larger websites that have thousands of blog posts.
