Maybe add an option to trade accounts, so for example: Person A offers CoC account, Person B offer CoD account, both asking around the same price. Both can trade their accounts over middle man if both are interested in the others account.
Trading is very time consuming. Sometimes we would spend hours upon hours working on securing trades which could stretch over the span of days, weeks even a month + for some games. We tried to charge users a flat fee $20 before to do this and most inquired asking if we could do this for free instead. It just wasn't a service in demand and one that is too costly to conduct.
