Like how a section on buyouts was added (a technical maximum, in which if it is reached the auction will automatically end with the buyout bidder winning) I feel as though a section on setting minimum bids would help, seeing as there are people setting minimum bids as well, especially since having a minimum implies the auction host would accept any bid that meets the minimum.
However with the current rules, it's difficult to understand if a minimum is considered to be a "top bid" and would have to be accepted or falls under the category of hosts being allowed to reject bids (with exception of buyouts, if one is set) At the very least, perhaps buyouts could at least be set in stone at the beginning, same as buyouts to prevent confusion.
