I had some fun once with "inspect element" while I were at my ex-girlfriends house. She asked me what I was doing and I told her about changing websites locally. I wanted to show her an example and so I went onto her school's website and played around a bit. I than changed the latest "News" post to a post about a food fight event organized by her school. She than took a photo from that post and send it into her schools WhatsApp group. They all went crazy how the school could do something like this and we had a good giggle. After a few minutes she told them that it was a fake and that they should stop believing everything that someone posts on WhatsApp. (Around this time a post was going around that was used to spread Missinformationen about the Berlin police)
