Honestly, reading this article was the first time I saw a documented case of strobes causing seizures. It's possible (and this is purely speculation) that the attacker sent the strobe to give some comedic punch to the statement "you deserve a seizure" not expecting or hoping that it would actually cause a seizure.

It's been common knowledge at least since the Porygon episode of Pokemon[0] in the late 90s.

It's possible but knowing people and the internet, it's more likely they were hoping an actual seizure would be the "comedic punch."

That protection should be offered at the video driver level. Anything less will be exploited by trolls.
