IMHO nostr has likes ("+") dislikes ("-") and emoji reactions. Emoji reactions should not be counted as likes or dislikes. Some clients/people always use emojis and never "+", others always use "+" and never emojis, and some clients/people can do either one. This is not ideal but it is what we have.
I wouldn't consider a post somebody emoji-reacts to as a post that they like. Gossip client, for example, has 2 separate reaction counts: likes + reactions.
But also, I think 1984 reports don't also need emoji reactions, and although the additional emoji reaction isn't wrong, it's probably a bad idea given what you have poitned out.
I'm beginning to wonder if binary likes are even really feasible. Having two kinds of reactions (likes vs emojis) cuts possible social signal in half, which doesn't seem great. Mapping emojis to likes appears to be basically impossible.
I only recently found out of + being positive and - being negative recently by manually looking up how satellite.earth tagged up/downvotes in it's events. I knew about holding the zap button in amethyst to get to zap settings so out of curiosity, gave holding the react button a try. Lo and behold I can change the reaction options! And + was a heart/- was a thumbs down.
Back in the day reddit was my fav so hope such compatibility for voting can be somewhat unified in a few nostr clients.
Though till learning of the - reaction, I considered ALL reactions to be positive. After all some dvms will no doubt provided content based on all activity a post gets and you wouldn't help someone providing bad content get more views.
