Gert downloadspictures from a website to make social media memes for her company. Her colleagues ask her where she gets her pictures and she readily tells them.Unfortunately, Gert has a suspicion that the website doesn't have permission from the photographers to offer their work for free. The website is violating copyright laws, and Gert is too, by using them.

If Gert is right in her suspicion, how could this lead to a tragedy of the commons?
