Here's an idea..."The winner's circle"
While top trending shows who has submitted the most favorable entries, it really has no bearing on who is going to actually win.
The winner's circle could feature the creatives who submitted an entry that is genuinely being considered, therefore restricting those entries from future submission. Sometimes there wouldn't even be anyone in the winner's circle because while there's likes or loves, they're not "the one". Also, it could always change. Just like a love can go to a no thank you, then right back to a love etc, one day you could be in the winner's circle, and the next you're not. BUT...your entry is only restricted from further use if you're in the winner's circle. A CH would only be able freeze up to 3 entries at a time because like top trending, there's only 3 spots available so they can't inadvertently monopolize a ton of names, and high ratings can still be given out to encourage creatives without freezing every good idea they've submitted.
This could be done behind the scenes where you're notified privately that you're entry is being officially considered and can no longer be used, but I really like the idea of knowing not only who is trending, but who is actually in the running!
Would anyone else prefer this or something similar over the current freezing policy??
