Yeah, actually the spec recommends a content of + or -, but allows for just about any kind of content in the reaction event. more-speech has 👍🏻 nd 👎🏻 buttons. When you hover over the reactions on a note, it lists all of them, who sent them, and what their content was. 🤙 is the most common because it comes from Damus. But you'll also see lots of + reactions from other clients.

I've never seen a - in actual use (except when testing.)
