Choose a random commenter from a post on Facebook.
- Install the Tampermonkey browser plugin. Tampermonkey allows you to install scripts that run when you visit a specified website. This allows you to customize your experience when visiting the site. Please use discretion when installing scripts, as they can be malicious. Only install scripts from sources you trust.
- Visit https://raw.githubusercontent.com/natematykiewicz/facebook-comments-random-winner/master/facebook-comments-random-winner.user.js and you will be prompted to install the script.
- Click Install. The window will close and install the script. (Updates to the script will be installed automatically.)
On Facebook, pull up any post that you'd like to choose a random winner for. In the top right, of the page (be sure to scroll to the top as Facebook automatically scrolls you down below the cover photo) you'll see a "Random Drawing" button. Click this button. You'll be prompted with a few questions, to know the rules of the drawing.
In order to choose a random comment as a winner, the script will click the "View previous comments" and view additional replies links, until all comments/replies are visible on your computer screen. This process can take a while, so be patient with it.
Once all of the comments are loaded, it will pick a winner. If you have multiple winners to choose, you can just click the button again. (This time around, it will be very fast, since all comments are loaded already.)
