It is a free market isn't it?
What do you mean ? this system is just to make more "protection" and less "scamming" .
Isn't going to stop people from scamming, nor will it prevent scams. You can't force people to agree to a trade and many wont bother especially scammers. Do I have to agree to do a trade with someone who is very likely a scammer just to be able to leave feedback when they try scam? What's to stop them leaving retaliatory feedback on me?
I know that there is nothing basically that will stop scamming , but this is just to protect users more I guess and make it easy to find scammers easily & just ban them for good . so they don't scam over & over different people
