The Oxford English Dictionary defines clicktivism as “the use of social media and other online methods to promote a cause.” It doesn’t only do that. It also involves organizing, facilitating, signing petitions, crowdfunding, and other things.
Social media makes it too easy to seem like an activist. One example of this is Facebook. On Facebook, people can change their photo to show an image that indicates support for a cause. I can say that I have done this. After the attack in Paris in 2015, I changed the image to have a filter with the the Prayforparis logo, which can be seen above.
Another area of Clicktivism is in the app store. Every once in a while apps are sold and all the profits go to a cause. I know that the Sims does this.
