missing article: is this group moderated?

On monday sept. 4th (UT) I posted an artticle under the title "opinion
poll on moon hoax and UFO´s" to this newsgroup. It was a supplementary
poll on one I do offline (in bars, on parties, etc.).

When I saw my article last time on this forum 2 days ago, friday 8th,
it contained 3 answers (which differed strongly from my public
results). On that day I posted my poll to another newsgroup (not
crossposting it, since I don´t want to keep the data from both
newsgroups separate).

And now I am looking again today, and I can only find my article in
that other newsgroup, but not in this one.

Is this a mistake of the Google server? Can anybody else here see my
article "opinion poll on moon hoax and UFO´s" on this forum? If this
forum were moderated, then the moderator would have the right to cancel
my article. But according to the Google newsreader this forum is not
moderated.

So if this forum here neither is moderated nor will I soon find my
article here, I will post it again and see what happens. Because none
of you knows my work hypothesis and data collection does not contradict
netiquette.
