Why is there a smiley face at the bottom of my WordPress website?

Recently, while updating my website, I’ve noticed a tiny smiley face in the bottom left corner of my website. I do regular security checks and keep my website updated all the time, so I didn’t think someone has hacked it, but still, I was a little bit concerned as I didn’t know where it came from.

Here’s how it looks:

What is the smiley face in the footer?

After a quick Google search, it turned out that the smiley face was being added by the Jetpack plugin. Why? According to Jetpack:

However, Jeremy Herve, the Jetpack plugin contributor, says the image is no longer being used:

So how do you hide the smiley face?

To do this, log into your WordPress back-end and go to the ‘Site Stats’ in the Jetpack menu.
