There is a usability issue when All around Qubes posts are linked to from the public. Users who can access it (i.e. trust level 2 or above) will be just fine. But the rest of the users will see the following:
Which looks like a broken link and provides no explanation.
There are two solutions:
- avoid linking to those other (more private threads)
- when mentioning those discussions add a link to this thread so people know what it’s about.
- detailed 404s
For detailed 404s, it is briefly discussed here:


Did you enable the detailed 404 page in your site settings?
That could be a bit less confusing as users would at least see:
The main problem is that discourse has a that as a binary setting. Either for all 404s or for none. And this has information disclosure risks, particularly for private messages. Not sure how to measure those risks, but I don’t thing such a site-wide option should be adopted.
If a more granular approach were to be adopted (i.e. only show it on categories), I think it would be a reasonable approach.
So for the time being, I think we’re stuck with:
- avoid linking to those other (more private threads)
- when mentioning those discussions add a link to this thread so people know what it’s about.
