Civilians might get a laugh to know
Ikes
is sometimes used for this, on the inside of social media database and software engineering.
There's no really good word that perfectly characterizes like, not-like, dislike and not-dislike {noting that not-like may or may not be the same as dislike, depending on the milieu .. not-like'ing a like on a post is totally different from dislike-ing a post .. depending on various things like what history is tracked, etc etc.}
Anyways
Ikes
is the smart-ass answer IF, that's if, in terms of my pithy and critical comment above ...
@pkuderov a critical issue is this ..... do you want this term TO USE AS A CIVILIAN DESCRIBING THESE THINGS. Or, are you a software engineer looking for the best term to use literally as a Class name, Parse (HAHAHA) Class name or the like ? If the former, probably "vote", if the latter, perhaps "mark" since "vote" is a more general thing. But see my pithy answer.
... if you were asking about the latter.
If you're asking about the former, it would be pretty awesome if "Ike" caught on in general parlance. So ...
Check out this post, did you ike it yet? Which way?!
... sort of thing. My local sports radio channel often discusses social media posts, you can imagine them saying something like
such-and-such got thousands of ikes, but half are likes and half are dislikes.
