We understand where you are coming from however we do not believe that this information is being misused in any way. Therefore, we plan to keep this feature at this point.
Our policies strictly prohibit anyone to register ideas that someone else came up with. This is why we now hide winning submissions that are not yet registered.
On the other hand, if someone comes up with a good name on their own, we encourage the creative to register those names. It is only a matter of time that a good name will get registered by someone. We would rather have creatives register their own ideas, instead of waiting too long and have that name taken by someone else.
Many times creatives make the incorrect assumption that the name they just thought of is very unique, and therefore if it eventually gets registered, it was likely done by the CH. This is often not the case. Showing these stats informs the creatives that other creatives have also thought about the same name in the past. It also serves as an important reminder that since multiple people are thinking of the same idea, it is only a matter of time that it will get registered.
We understand unwanted domain registrations are not helpful to anyone - and our goal is to continue to offer tools and features that allow creatives to secure their good names as soon as possible.
