I built a regex to recognize this. It looks like this

I tested it here

I setup a content monitor with this regex string to detect this but it does not work. It reports trouble. I can find no documentation on your site about the regex feature or how it should be used. Can anyone help?

The actual site is https://or-beta.nmdp.org/robots.txt

You are free to browse that link or make a test on it yourself if you like. Just remove your test when you are done so we don't see your traffic long-term.

Thanks for anyone who can help.
