Have you reported it? I just did, saying: "Insubstantial thread", and I expect it to be gone as soon as a Mod sees the report.
Or are moderators waiting for people to report?
Of course! Mods can't possibly read all posts/topics.
Meta doesn't have it's own dedicated Mod(s), that means only a few Global Moderators have to take care of this and many other boards.
I just did after seeing you reply. Both threads. I had some recent reports marked as bad and I am a bit unsure when reporting because as I cannot see the feedback, i don't know what I did wrong but that won't be a problem in the near future.
