Don't take this the wrong way: Being indexed by Google does not add anything for me personally, as I am not using Google. If there is a forum, which can only currently be indexed by Google, then I might even see that as harmful to the web in general, as it adds incentive to users to use Google, instead of other search engines.

I have experienced it multiple times, that stuff is only in some discourse forum and I see a blank white page. Basically a JS-wall. Not sure, if the people, who hosted it did something weird to cause that issue, but that is the impression I have of discourse forums. Rarely I allow its scripts to run and make the effort to view some content in any such forum. Usually I just close the tab.

Edit: Now I know why I might have had that experience: I also block loads of third party CDNs. Perhaps they were trying to load scripts and resources from there and that's why nothing was shown.

Edit2: But you are also correct: The Nim one does not show anything without JS.
