Thanks for clarifying things. I see the drawbacks of the old system and I certainly see the drawbacks of the current system. I don't know what the best solution is, but for the sake of transparency and expression, if YouTube were to revisit this issue, they should give creators the option of enabling CAPTCHA to register likes/dislikes on select videos. It would weed out the bots and the casual brigaders. It might impact genuine like/dislike engagement on select videos, but maybe this can be mitigated by adding the benefit of bypassing CAPTCHA for YouTube Premium members.
As an aside, because I've been sucked into many a YouTube shorts vortex, I would like to make the observation that the utility of the like/dislike buttons on YouTube shorts has evolved them into more/less buttons. And it isn't even corresponding to a particular creator or their content, per se, it's mainly about assisting the algorithm in curating a personalized feed of content types. So, from a content consumer's perspective, the transparency of like/dislike totals is essentially rendered meaningless on YouTube shorts. Had to get that off my chest. I've suffered in silence mindlessly teaching YouTube that I like brief funny animal compilation videos long enough.
