I think that the way auctions are currently handled on accounts is rather flawed, this is how I think it could be improved. People sometimes start a bidding war over a BIN. That's not how a BIN works, you hit it, you win, you shouldn't be able to bid over a BIN. Offer system - This seems like an evasion of rules to me. Essentially, it's not an auction and the auction rules don't apply to the seller, but they do to the buyer, that doesn't seem fair to me. Buyers should be able to back out of offers if theirs hasn't been chosen by the seller. New members shouldn't be able to partake in auctions until their account is a few weeks old. Reason being: I've seen a few auctions in the past where a new member started a bidding war, then got banned for evading or attempted scamming and then the person who was in the war with them gets left off with a bid 50$ higher than they originally had, essentially, the auction is upped and the buyer gets screwed.
