Lauda, how old are you?
Old enough to treat everyone equally, and old enough not to let people extort me into removing ratings (I was told to remove my rating in order to bid on the auction)
I don't think you understand what extortion means. You should probably look it up. There is no reason why your ability to bid on his auction is worth anything and it is within anyone's right to decline to do business with anyone else for any reason or no reason at all.
I think you should clarify your age. I don't think you are mature enough to act impartiality.
