When blogger and PR agent Wanja Lange kept receiving unwanted photos from various men, she finally got fed up and decided to take revenge.
So she shared the content of her inbox with her 35,600 followers on Instagram, posting blackened out pictures of the explicit shots they sent her.
Lange told the Sun Online: "I felt violated and disrespected. It's a violation of my personal space.
"It's an act that is no different from other sexual harassment or assault and I believe that it gives the abuser the same kind of "kick".
"It wasn't even a question for me where I should share it or not. Anyone who sends me an unsolicited d*ck pic these days will be exposed."
