Every bid goes up 5%. When the bid doesn't go up 5% you've reached the max bid. For example, people like me who put up a round number max bid make it blatantly obvious. Let's say I put a 100,000 max bid on a 72,592 item. All the seller has to do is shill up to my round number and stop. Here's what the bids look like: 72,592 >> 76,222 >> 80033 >> 84035 >> 88236 >> 92648 >> 97280 >> 100,000 (instead of 102144; Max bid reached!)
Here's a simple solution: Make ALL the displayed bids 5% higher. Or is this working as intended? I've been burned so many times by this already. Don't place max bids!
