Customers have expressed their dissatisfaction with CreekEx. The fact that it is no longer operational demonstrates how awful things are for the exchange. I was able to get some data during the periods that it was active.
According to these figures, the exchange had a small number of clients, and the majority of them were unhappy with the exchange's withdrawal limitations and costs. Furthermore, there may be some delays in the exchange's transactions.
I couldn't locate any customer feedback, so I'm not sure whether any of the exchange's assets survived after it was shuttered. I couldn't locate any security information either. The exchange is no longer functioning, and none of the sources have adequate information about it.
