Twitter trolls hijack Epilepsy Foundation hashtags with strobing images

In 2016, a troll deliberately tweeted a rapidly flashing GIF at writer Kurt Eichenwald, who's a known epileptic, to cause a seizure. It unfortunately worked, demonstrating how social media can be weaponized and used to cause bodily harm. Now, the Epilepsy Foundation has revealed that it suffered a series of similar attacks on the platform.

The organization, which has already filed formal criminal complaints, said the attackers deliberately mentioned it and used its hashtags in tweets with flashing or strobing light images. Even worse, it happened during the National Epilepsy Awareness Month in November when more people with epilepsy were likely monitoring its feed.

Epilepsy Foundation chief medical and innovation officer Jacqueline French, M.D. said there aren't a lot of people suffering from photosensitive epilepsy, but that attacks could have serious impact. "Many are not even aware they have photosensitivity until they have a seizure," the doctor said. The organization's director of legal advocacy, Allison Nichol, also explained how egregious the attacks were, seeing as Twitter is one of the largest virtual places where people can gather online.
