The first rule of scamming is NEVER scam on your main account. Look around a find a scam to get you a shit account with game time.
The second thing, don't change it to 0 gold, change it to a lower amount that still looks like the original amount. For example, if you're trying to scam a blessings deck, put up 1500g, wait a few seconds so they can look and quickly erase the last 0 to turn it into 150g. On a quick glance they'll rarely notice the difference, and the 150g "lost" isn't much compared to the 1.5k and keeping your account unbanned (Although you SHOULD NOT be using your main for this!)
