What kind of effect does knowing exactly which people downvoted you have on a platform? Is there a chilling effect on downvotes, is there revenge downvoting? I guess we’ll find out.

It’s not like we haven’t had public downvoting in the fediverse yet. We already found out in the past.

Kbin had public downvotes and the main effect was that people put more thought into their downvotes. While I assume it wasn’t without abuse, I’ve never seen it brought up as an active problem, just something that could theoretically happen.
