You missed the point.
The point is sellers are selling good equipment as parts because buyers will complain about non existant issues.
I was booted from a forum that had members out in the open discussing strategies to harass and defraud honest sellers. When I pointed out what they were doing was illegal and against ebay TOU they turned against me. But not before I alerted the sellers they were plotting against with links to the posts.
People will get in over their head with a purchase (new or used ebay or not) and blame the seller, the don't read instructions, they don't read descriptions, they don't understand TOU etc. Buyers will buy something listed with known faults and expect the seller to pay for the repair after they buy it.
I was a power seller on ebay a couple years ago, I rather throw stuff out than sell on ebay right now. Meg @#$%man screwed up ebay and lost a ton of sellers and buyers.
The BAD BUYERS are looking for freebies through any means legal or not.there are bad sellers too, but bad buyers abound.
