@Nelmag Could you please share the details of the specific instance via the chat window? Once a customer owns a domain name, they can technically resell it if they are not using it - however launching a contest for the sole purpose of reselling a domain name is not an appropriate use of our platform. If we find that a customer is engaging in such a behavior, we will likely not allow them back on our platform. We haven't seen many instances of this happening, however if we do see repeated instances, we will likely update our Terms of Service to explicitly disallow such a practice.
On the other hand, we have also seen some instances of winning domain names from the winner board getting registered by someone other than the CH. This is the reason we added a 3 day delay to allow enough time for CH to register the domain name before it is visible to everyone. It is also possible that the CH may decide to go with a slightly different variation (from what was selected as winner), and therefore the winning name might stay as unregistered even after it is displayed on the winner board. In these situations, it is possible that someone might register that name, and resell it elsewhere.
Therefore, if you see any such instances, please report it to us and we will investigate them.
