hey good question, and it is experimental so we'll see how far it goes, but I think you could get more granular to detect things like unique message author/over rolling time period, account age, perhaps a private vote people could add or other metrics to try and filter out noise.
To follow up with that, I want to try and mimic real life as much as possible, and avoid the incessant dopamine feedback loop that voting/liking promotes. That's sort of my guiding idea, to keep it razor focused just on conversation.
