Some cool example is: Let's say we have website A, in that website we can create our profile with our name on it. And one more thing: website A doesn't sanitize or escaping the user input.

So What will happen is:

Good People Input John Doe, so his profile name can be seen as John Doe.

Bad(sort of) People Input <b>John Doe</b>, so his profile name can be seen as John Doe.
