The worst trading system in existence.

There are dozens or hundreds of complaints about the trading system in the chat every day.
While selling the warehouse for the exchange,
I wonder why they don't just automatically create the transaction.
There are a lot of fake items listed to check the price,
and fraud using manual transactions is rampant.
Does it make sense that the 20-year-old Dungeon & Fighter trading system is much better ?
Since trading isn't an auction,
the seller sets the price and the buyer just buys it.
It should be a really easy and simple thing.
I can't understand why they've dragged this system into 2.
