       | and Roblox are scriptable.

       | not just moderation to protect people from being offended, it's
       | moderation to keep people physically safe. We need to take this a
       | lot more seriously than we currently do as an industry.

         | content will somehow leave a greater impression than normal.
         | 
         | In my experience, this doesn't happen. I find the content
         | equally disturbing (or not), regardless of whether it's on a
         | phone, desktop or headset.

           | brightness difference.
           | 
           | You'd have to measure changes over a longer time and possibly
           | predict into the future.
           | 
           | Maybe you could get away with detecting single frame
           | brightness changes over a threshold and sort of smear the
           | change over a period of time. Similar to that awful temporal
           | shader that so many games use now.

       | accounts for ~3% of all diagnoses of epilepsy.
