@klrmn This rule needs additional refinements.

There is couple of links with `#` on this page, but they lead to different web-site. And this sounds like a bad idea.
We can filter URLs with `#` but only if they are for the same web page that is under test. So, if we are checking:
`https://mozillians-dev.allizom.org/en-US/about`, we can omit URL like `https://mozillians-dev.allizom.org/en-US/about#LALALA`.

I might be wrong, but this is not javascript URL. So maybe I just misunderstood your idea.
