I have an idea about preventing fraud when trading.
Transactions should only be processed through intermediaries. And there is a third party reputable enough to hold this money. And also server files, for sellers.
I recommend none other than MentaL.
Whether accounts are allowed to be sold or not has been discussed a lot before. For example: registration time, posts, account status (regular member, sales vip member...).
That will partly limit scammers with little capital. Haha. However, they need to demonstrate their trustworthiness, then they will have prospects in sales.
Next, when buying/selling. Buyers need to deposit 100% of the game server's amount on the forum system if they want to trade through the forum, the price must be clearly listed, this amount will be kept in a 3rd party wallet. Is the person I mentioned above.
At the same time, the seller also needs to deposit all the files he will sell on the forum.
In addition, any other form of transaction, if posted for sale on the forum, will be prohibited. Because if they trade outside, they have to bear all the risks themselves, and we should not be responsible for those cases. Therefore, the forum's reputation is completely unaffected.
To avoid the problem of receiving the goods and getting a refund. We must first test the game before it goes on sale. And the seller must put all the files on the forum, so that it can be sold like amazon. Even auctions, like ebay. Haha. To be able to list goods, you must be a VIP account. Account allowed to sell, paid for this feature.
After the files have been uploaded, they will be inspected, and the seller is obliged to provide full operational methods to save time on inspection. If there is a video it would be even better. It will be a document for the buyer, and the review team.
Let's say RZ is an amazon warehouse, and the seller ships their goods there. The quality of goods has been tested. If the buyer doesn't buy, it's ok. But if you buy it, you can't return it because it's a digital good.
I don't know if I'm thinking too far ahead, when I'm thinking about the future where MentaL will be a second Jeff Bezos.
