Found a post on VeryGoodPlus, and actually:
First time I see this, there are huge amounts of bootlegs on sale there, so maybe they need a word from the rights owner?
and not only bootleg it looks, even promo album not for sale!
Interesting. I wonder if eBay are being pressurised to do the same? Of course, eBay are much bigger and more powerful than Discogs, so they would presumably be a lot harder to intimidate!
On ebay you can have items removed for a single vendor, somehow it works. I don't think it works on Amazon, plentu of pirate cds there too. But if I red well, on the second link, they are not talking about a bootleg but about a legit promo album "not for sale" at the time of its pressing...!
They are supposed to sell the site so they clean it ip before.
