Fun fact: sharing this link on Mastodon caused my server to serve 112,772,802 bytes of data, in 430 requests, over the 60 seconds after I posted it (>7 r/s). Not because humans wanted them, but because of the LinkFetchWorker, which kicks off 1-60 seconds after Mastodon indexes a post (and possibly before it's ever seen by a human).
Every Mastodon instance fetches and stores their own local copy of my 750kb preview image.
(I was inspired by to look by @jwz's post: https://mastodon.social/@jwz/109411593248255294.)
