New trading system

Starting with my appreciation for the new system, we really need some changes and the possibility to sell item while we are mapping, afk or offline.
Today, while watching another game on Twitch, I was reminded of a problem that plagues many games these days: cheaters!
My biggest concern about the new system and being able to interact directly with my sales tab is: what if someone cheats to get my items without the currency in exchange? are my items safe? do we have a working anti-cheats?
I really hope that's not the case, but I really think someone is already working on a way to exploit the system.

What if someone cheats in the current trade system, and completes an in person trade with you, but you never get the items they offered?

What if someone cheats and impersonates you IRL, accesses your bank accounts, is prettier than you, steals your wife AND your dog?

The "What if" game is stupid.

The asynch trade system is better across the board. Needing to prevent hackers and exploiters is a constant no matter what trade system is in use.
