I don't know what to say.... if this is true, then the release should be removed from Discogs. We can't even ask to the original submitter, since he is not on Discogs anymore

Well with only 1 ever sold, I found Discogs cannot be trusted the release really exists. I have seen several never-released versions on Discogs that many said they owned that the band told me was never released!
When another similar release was released, Discogs keeps saying the original release was sold over and over when the "original" NEVER existed. I own many of the real releases that keep being sold over and over on Discogs, but as the wrong "versions" that were never released.
Additionally, many variants of the same versions are called other versions on Discogs that are exactly the same release, except for differing codes on the CD's read with a magnifying glass.
