I just read a thread on the German forum Philaseiten.de , with a similar discussion about fakes on Ebay & Delcampe. Someone pointed out in April 2020 that when selling on Delcampe, “It is no longer mandatory to indelibly mark counterfeits, copies and imitations approved for sale. Nevertheless, the nature of the article must still be clearly indicated in the description.
A representative from Delcampe responded by quoting their current rules, which I have copied from the English version of the site :
"5.1.3 : Questionable items
- Fakes, copies and reproductions. Delcampe forbids the sale of these items. However, an exception is made for fake stamps, coins and postcards, which can be collected. The sale of these articles is acceptable as long as the seller fully spells out the nature of the item in capital letters in the title and description. An abbreviation is not sufficient. The term used must be selected from the following list, based on the type of item : Reproduction / Forgery / Copy. Fake postage stamps and coins made after 1945 are prohibited.
So interestingly, it appears they made exactly the same rule-change as Ebay did a couple of years earlier. And as with Ebay’s policy which segregates counterfeits from replicas, there is no further guidance on how they intend to distinguish the terms reproduction, forgery and copy.
The 1945 rule at first glance seems to be a simple and effective way of stopping most of the fraudulent activity currently going on. But it still leaves the problem of who will police this, and how. The Forum members immediately questioned the Delcampe rep about this, who gave the typical Ebay line of "Report it, and if necessary we'll take action", with no explanation of how. It appears that they have a team which includes voluntary unpaid moderators who can cancel listings - some of whom are members of the forum. What fun we could have, if Ebay introduced a similar scheme!
But even if they added a similar 1945 rule, Ebay would presumably still fall back on their argument that "We don't handle the items, so we can't judge what is a pre-1945 reproduction, and we don't know the motives of those who report alleged fakes". And thus do nothing, even when knowledgable specialists report an item.
If anyone here is a member of Delcampe, it would be interesting to get a "horse's mouth" explanation from their policy team of how they police and enforce the "no fakes after 1945" rule.
If anyone would like to read the German thread, here's the link. It has an English translation available. The thread begins back in 2012, but quickly moves forward to 2020. The post about the indelible mark rule change is numbered 27.
