Automating Deselection and Unchecking of Twitter Interests - EvilTester.com: The final JavaScript works to automatically deselect Twitter ad interests, but I had to change the timer from 2000 milliseconds to 10000 milliseconds or 10 seconds per uncheck to avoid Twitter Over Capacity errors. The process is taking forever but isn’t invasive at all so this Safari JavaScript console automation can go all week for all I care. By Twitter’s estimation, I am interested in everything in the universe. Including things that greatly raise my blood pressure. Ugh.

From the above website but milliseconds modified from 2000 to 10000. Paste and run in your browser’s JavaScript dev console when on the Twitter ad interests page:

var timer=100;document.querySelectorAll(
"div > input[type='checkbox']:checked"
).forEach((interest) => {
setTimeout(function(){interest.click()},timer);timer+=10000;});
