Since I was curious about China_Cards I went looking for his offerings by doing a search on Seller. What I found is that he also has a second account under the name Chine_Cards which is not suspended. In addition he is using the second image to advertize various websites such as one for making your own fragrances. In my opinion this is a form of SPAM and should not be tolerated. Considering the variety of websites he is posting it appears that he might be selling advertizing on his listings.
Also, while I dislike critizing another seller,

I have taken a look at a couple of his banknote offerings, which is what I specialize in. In one case a Hong Kong 50 Dollar note was offered (he lists it as a 50 Yuan). First he shows an image of several of the notes, but is offering only one. This is misleading especially since he does not state in the description that the Buyer is only bidding on one note.
Second, he is using a Chinese catalog number to identify the notes, instead of the Standard Catalog of World Paper Money (Pick Numbering System) which is the world standard for identification of banknotes. It is fine if he is only selling to Chinese collectors, but not to an international group of collectors.
Third, no year is mentioned for the note which may effect it's value.
And finally no condition is stated although the note appears to be uncirculated from the scan.
If it were not for the quantity of his listings my first thought would be that he is just a beginning collector trying to sell off his collection rather then a dealer, and does not know any better. In my personal opinion Delcampe should take a closer look at this seller.
