We do not allow Creatives to ask CHs directly about reported domain.
Squadhelp manages the communication with CHs regarding domain registration because we do not want a CH to get multiple messages from SH team as well as Creatives about domain registrations, especially because the vast majority of domains are not actually registered by the CH.
When a domain registration is reported, we already send the CH messages and followups. In cases where they confirm that they registered a domain, we also inform the CH to either select a winner early and close the contest, or send the bonus to the creative. They also have the ability to pause the contest in case they are not looking for any additional names.
If a contest is active, and a CH is continuing to provide ongoing feedback, it is a strong sign that they have not yet found a winning name.
