You have a fiduciary relationship with the paying customers of your service. One player cheated around $10,000+ (conservatively) into the economy. This devalued the value of every real world $ bought ce. Then you said no harm done as it was mostly all used on punch (this is completely asenine. This is a bold faced lie. This is a pathetic copout. This is a deception to your players as a cover your own a. Truly pathetic).
Is this even legal for you to allow the crowns to stay in the market since? It was you negligence in programming that ALLOWED this to happen.
