Damus has 🤙. It's an emoji reaction. 
Primal does count 🤙 next to the +.

You actively don't count reactions, you filter reactions. Why blame other clients? Even if you don't care about the emoji and don't want to add it, still a kind 7 event exists and you guys filter it out instead of just counting it. And please understand I'm not trying to blame and critic here, I just want to make you aware that your users might be happier to actually see reactions they get on their notes. Even if you count all kind 7 reactions just as a heart(+), people know someone interacted with them. Am I wrong about this?
