First, perhaps read what I wrote rather than just the title, because I am guessing with 102% certainty that you didn't.

Second, "seriously": personally I prefer the idea of a world where people take each other seriously. Where they treat each other with respect, understanding, tolerance. No, that is not the world we have here, and in any case it seems you've given up on it already.

The data about downvoter identity would need to be either embedded in the HTML (ideal but I doubt it) or available for async JS via an API (complicated and slow). In any case I don't have the time so in practice I will just have to put up with it or leave.

But yep, this feature would clearly be a task for front-end scripting.

Fair enough (indeed, I agree) but that is not what I am asking for here.

If I am "sensitive", imagine what the average must be! I'm not at all what you're imagining. Nobody would call me sensitive. I'm super argumentative, I'm the one who speaks up in groups, I'm the one who gets angry and makes a scene in the shop. At school I would stand up for people being bullied. So this is really a bit of a misunderstanding. What I don't like is exactly that: bullying. And spitefulness and herd behavior, i.e. groups targeting individuals. It totally triggers me and this is how I see downvoting, alongside all the needless insults and mockery and juvenility.

Cards on the table - I've been on the edge of the social internet since the 90s and I think social media has become a disaster for society. I had hopes for the fediverse (no advertising algo incentives), and it is better, but only marginally. It seems humans just tend to behave badly when they can hide behind screens.

And to be clear, I never asked to "ban" anyone. Of course not. I just want not to have to see people who raise my blood pressure. It would be totally possible technically.

So I'm not the only one after all. Thanks for the moral support.
