So I just saw this edit in the review queue:
https://security.stackexchange.com/review/suggested-edits/140434
The user wants to add a big warning and a bunch of scrolling distance to hide a flashing image from those to whom it might be harmful. I rejected the edit because it seems overly destructive to the post. But it begs the question: how do we handle this?
For now, I will just remove the image. I will post the reasoning as an answer, since it gives one possible answer to 'how to handle this'.
