I found this emoji, that we call moai: 🗿 and I used it quite a lot, perhaps because I was highly influenced by my friend who too used it a lot.
Another friend of mine (who is quite a riddler) pointed out that I have been using it too much and it was turning into irritation. So, like any other decent human being, I stopped using it.
I was later pointed out by that same friend that I had not been using that emoji anymore and why so. Now I was puzzled. It was the same person who got irritated due to me using the same emojis again and again. And then the same person asks me why I am not using them anymore.
Anyway, here is some information about the Moai right from wikipedia
