The tool you use, can it create a list or so with all comments containing something specific, like a passphrase or similar, and then only take the first created comment (including the phrase) from users that are not bots and create a list from that? In that case "guess the price" answer tracking would be fairly simple.
I quite like that idea actually. If it's possible I should do something similar in the Hive Poker community. Just need to get fully back to health again 😊
