For example someone liking controversial content

On reddit you basically have to sort by controversial today and lemmy isn't far behind. There is a hive mind today where people jump on the hive mind and hate wagon. And public voting will increase that, the whole idea that we need to watch out for the dissident malicious actor stalking social media attests to that. That is something that needs to be tackled through a kind of automated or extremely efficient moderative response to detect bots and voting patterns of malicious actors. Of course the question is if anything can be done at all against this shift in zeitgeist.

What is needed would be a way to anonymize voting through some kind of clever algorithm or blockchain or token or something. Or maybe that can't work or then prevent any protection against bots.
