If a topic is hidden/deleted/suppressed, and you don't have the rights to unhide or restore it (e.g. you're not logged in), then you don't see the topic box at all. This is great on a Flow board, spam is invisible for people who can't reveal it.
But if you follow a link to a flagged topic and don't have the rights, you see an empty page containing just
<Flow board name in h1>
It looks broken.
If you have the rights, then you see
<topic title in h1> "This topic was started on <Flow board name>" gray link line [This topic was deleted by Admin] topic box
I think users without rights to unhide/restore should see something like
"Flagged content" as h1 "This flagged topic was started on <Flow board name>" gray link line
the details will change if we add a crumbtrail from topic back to post.
