With the use of shortcodes it is possible to react to the content by emojis. 
So you install the plugin and create new emoji with a title an emoji itself, a count field and an initial count, to fake the initial value of the clicked emoji. 
The shortcake is [emojized id=“8” count=“true”] (or false or empty)
In the new version you can limit votes to one per user.
This plugin demands WP REST API plugin.
