TIL #Discord effectively does traffic amplification when users post an image. They crawl the image URL using a Discordbot User-Agent, but in the same second request the same URL with a spoofed Mac OS browser User-Agent that can't be identified as a Discord request.
Both request are required for the image to render in Discord chat. Absolutely great!
