Except leaving first bid from Hero member account other bids are from Newbie , how can you trust a newbie account bidder and proceed your biddings , This can be assumed that your alt are raising the bids , if you want to do the auction it is better that atleast the member should be Jr.Member rank, newbie will just raise it and run away even if they win , their account is not worth that they dont mind it to scam.
I don't own the newbie accounts.
If they will run away if they win i'll choose 2nd highest bidder.
Most of account buyers are newbies - alt accounts of someone trusted or alt account of scammer.
Everyone can bid on this account and if they are not interested then i choose 2nd highest bidder.
