This has been suggested before but it doesn’t work like that. It sounds great as a buyer but it has many underlying issues.

E.g. It’s the seller that gets to chose what items they want to sell their items. If they implement this then that power is taken away from the people that pay thousands of dollars on plat. It’s the same for people that spend hours farming to have someone tell them what’s their time and effort worth.

There is a reason why no game does this to begin with.
