The cyberattack on the Epilepsy Foundation’s Twitter account convinced Twitter to take some proactive measures like banning animated PNG files on the social media platform.

Weeks ago, pictures of animated strobing lights targeted people with epilepsy on Twitter’s Epilepsy Foundation’s handle. Although the attacks didn’t involve APNG files, they did use similar animated formats.

After looking into it, the company discovered a bug that allowed APNGs to be used several times in a tweet, bypassing autoplay settings. To prevent such files to be used in a future cyberattack, Twitter decided to ban them altogether.

“We want everyone to have a safe experience on Twitter,” the company says in a tweet from the Twitter Accessibility handle. “APNGs were fun, but they don’t respect autoplay settings, so we’re removing the ability to add them to Tweets. This is for the safety of people with sensitivity to motion and flashing imagery, including those with epilepsy.”

After all, animated images are not just potential triggers for photosensitive people. Just four years ago, a GIF sent to a journalist with epilepsy led to a terrible seizure. Now, animated images are considered a deadly weapon.
