Good evening,
I was thinking about a problem that is very common for those who use market to make some extra cash: fake buyers and fake sellers. Noone of them seems to care about reports.
In my opinion, to discourage this type of behavior, you could insert a sort of flag system.
Once the faults of the fake buyer or fake seller have been proven through the report system, the moderator flags the person in charge.
The first flag is just a warning. From the second flag onwards, each flag corresponds to a penalty of 5k pokedollar in this way.
When you sell or when you buy, you pay
5k pokedollar x flag taken
to the system as a "tax" of past bad behavior
Honestly, don't know if this could be an hard job or an easy job for the developers, but is more efficent, in my opinion, than 1 or 3 days mute ban.
Greetings
