I think that a user noticed something possibly wonky with image uploads and mentioned it in the proper forum for fixing stuff. Then somebody decided (or was being a wrecker, can’t remember which) to test out the issue.

Someone tried to upload a massive image file of a pixel art DPRK soldier and crashed the site. I don’t remember the specifics, but I think it was something along the lines of the image hosting service/program trying to load the whole file into RAM and leaving none for the other stuff running on the server. Antics ensued.
