I am posting this in the hope that Sebastien Delcampe is still following this thread. Let me say that I do appreciate the efforts made by Delcampe to keep the auction site clean and free from scams and forgeries.
I know this is a very difficult job and it is not always easy to draw the line, despite the guidelines outlined by Delcampe in this thread. Early November 2012 Delcampe has apparently banned all postally used State of Oman
covers as well as State of Oman labels.
I do not think it is appropriate to ban postally used covers. The ones in question were sent by the postal agency of the exiled Imam of Oman's organisation (or "government in exile") to dealers and journalists world-wide. Covers fabricated by Youssuf S. Tadros of Middle East Stamps in Beirut with State of Oman stamps were accepted by post offices in Baghdad (1968), Amman (1968-1971) and Damascus (1972) and mailed from there to destinations all over the world. There was nothing illegal about this, everything was done in accordance with UPU and Arab Postal Union regulations. The covers haveseen genuine postal use, no matter what one thinks about the political and commercial motives behind these issues. The only "lie" was that the covers did not come from Oman and then went through Baghdad/Amman/Damascus in transit - they originated there.

The State of Oman affair is an interesting piece of political and philatelic history, and, yes it was a scam in a way. But I would not have been able to study and document this affair if I had not been able to buy original material on auction websites.
I have written several articles for philatelic magazines between 1969 and 1972 when these "stamps" were put on sale, informing and warning collectors not to mistake these labels for stamps, especially not for the stamps of Muscat & Oman / Sultante of Oman. I have been in touch with the Sultanate's PTT authorities then and adised them to send a warning to the UPU once the had joined.
But this is all history now. The original agent for these "stamps", Youssuf Tadros, stopped issuing them in 1972 when he could no longer produce postally used covers. Clive Feigenbaum carried on printing State of Oman and Dhufar labels until 1986.
By now, all these people are dead. The ones selling the labels on auction sites etc. are not those who invented the scam and printed the labels to make money. They are dealers and collectors like you and me who bought them. They may not be stamps in everybody's definition, but they are collectable items. There is a market for them, and my observation is, that (apart perhaps from a few topical collectors) the buyers know the story behind the labels and buy them in full knowledge of what they really are. If anyone is in doubt, he will find a note as to the status of these labels in SG, Scott or Michel - he does not need to have read any of my ephemeral writings.
The market for State of Oman labels is actually so good that some really bad guys have started to produce forgeries or new varieties of them now, 26 years after the notorious Clive Feigenbaum produced the last of them in 1986! I wish Delcampe would ban these forgeries and not the original labels!
Sebastien, I hope Delcampe will reconsider their ban at least with regard to postally used State of Oman covers, or even allow the sale of the labels themselves if properly described as labels or bogus.
