Pete, it works exactly the same as Ebay's condemnation of bootlegs. Advertising them is not allowed, selling them is not allowed. Both happen frequently and often on multiple items. They might even get reported by numerous folk on here, to no avail because they can't be ar$ed. But they do have the power to act and just occasionally might.
I heard of an Ebay/Paypal transaction where a very expensive violin was traded. The buyer professed it was a copy. Paypal refunded but Paypal(or Ebay) demanded proof from the buyer that the violin had been destroyed!
Now wouldn't that set the cat amongst the pigeons if they did the same with vinyl.lol.
Stay lucky!
