In #amethyst when you are adding emojis, if you just tap the space bar ONCE, you can save it and then use it on other posts to PREVENT other posts from getting reactions from people.

When you use the the space you saved as a notification on someone's posts, it locks it from getting anymore reactions

Notice how there is still heart on the post above and on the comment below it, there's just a number?

Can't emoji the post anymore. I'm gunna be such a dick lol
