Over the years, social media site Reddit has done multiple pranks and events for April Fools' Day.
[5] For April Fools' Day 2014, Reddit did "headdit", a joke way to navigate and use the website using the webcam.
[7][8] For April Fools' Day 2015, a social experiment subreddit called r/thebutton appeared.
[10] For April Fools' Day 2016, another experiment was launched involving the "Robin" chat widget.
After clicking a titular button, an IRC-like chat window was opened with one other user, and allowed a certain time to pick among three options: "Grow", "Stay" and "Leave".
Place was closed on April 3, 2017, at 1:00 PM GMT having been active for a full three days.
For April Fools' Day 2019, a social experiment subreddit called r/sequence was released.
The experiment consisted of a community-driven sequencer that users interacted with by submitting GIFs or text slides to be compiled into a movie.
At the end, once the entire sequence was filled, it was posted as a full story in an external page.
Before the event ended, users were only allowed to place white pixels, reverting the canvas back to its original state.
