I thought of a solution...

Excuse my english is bad i use translator.

I play to poe1 and poe2 long time...

I think the trading system is broken. Players who do not give an answer when you want an item and the guy doesn't respond, it wastes a lot of time.

I thought of a solution...

Imagine a rating system similar to the website Reddit. A way to give a rating, a point system to the good seller who responds, or to remove a point from the seller who does not respond.

Over time, players will make a good trades and be more responsible for their sales.

A bad seller would lose credibility wth online players community.

It's simple, if you post an item for sale, you have to respond. If you don't want to take care of your sale, Withdraw your sale.

A point system solves everything.

Thanks to share this idea.

it would be weaponized.

Yeah, this idea just doesn't work in free to play games where anyone can make bot accounts to trade themselves over and over and over again to push their own rep up and push everyone else down.

Also, just as a general rule: if you ever find yourself looking to Reddit as an example of how things should be done, you're wrong.

In an ideal world this would work. Then again in an ideal world people would always respond. Unrealistic. We do not live in an ideal world and that makes this suggestion equally unrealistic. Did you consider what people would do to get ahead within your suggested system?
