JunoWhom was looking for a specific "lost" pony image, and it was found! See this post and the next 3 posts after it:

I made this nice code which saves upstream Derpi uploads info locally as JSONs and downloads two corresponding things from the remote server:

I suspect that this guy https://desuarchive.org/mlp/thread/41556719/#41567307 is a troll. Details later in that thread; warc of it:

Additionally, he posted this at the same time in a thread he was linked to: https://desuarchive.org/mlp/thread/41526413#41568045 . Timing:
