Havining forwarded some 50 mails to spoof@eBay now, further replies point out they cannot prevent spam being passed via contact the seller and I repeatedly point out they did not appear in 'My mesages' of 'My eBay' so they were not via contact seller.
I think they deliberately play dumb so you give up and find something more useful to do like demolishing a wall with your head.
And then I get a customer satisfaction survey which I filled in appropriately which seemed to keep repeating itself, sub-conciously it tells me find another wall to demolish ok, will do
