From what I've heard eBay basically just dosent care about sellers
apparently if you don't accept returns on an item
the buyer can still return the item anyway even if it says "no returns accepted"
and there was some glitch with the bidding thing
were you could bid any amount of money on an item without having a payment method on your account
for example if there's an item up for bids and the starting price is £5 you could you just put in £2000 and win the bid without having a payment method so you could win any bid without spending a penny
