Referrer spam

Imagine you have a special book that you love reading. Sometimes, when you finish reading the book, you want to tell your friends about it. So you ask a grown-up to call them and tell them about the book. This grown-up is called the "referrer".

Now, imagine that you have a website where you write about things that you love to do. This website has a special tool that helps you know where people come from when they visit your website. This tool is called Google Analytics.

Sometimes, bad people use computers to visit your website and pretend that they come from a different website. They do this because they want you to think that people are visiting your website from that other website. But actually, no one really visits your website from that other website. These bad people are like a group of kids who tell lies about the books that they read just to feel important.

This is called "referrer spam". It's a bad thing because it makes it hard for you to know where people are really coming from when they visit your website. So you can't tell which marketing strategy is working and which one is not. Just like how it's hard for you to know which book is really good and which one is not if you only listen to the lies of the kids.

So, it's important to block these bad people from pretending to visit your website from other websites. Just like how you should tell the grown-up to not listen to the lies of the kids when they talk about books.
