At the moment the problem is mostly the other way around: Mastodon preview fetches function as a DDOS on your site; given the intransigence of the Masto BDFL on this problem, I would be delighted if it were inverted.
I don't understand. This looks to me like a Medium page that embeds a Mastodon post, hence preview fetching lands on the Mastodon's instance?
That's what the post describes. However, confusingly, the very first screenshot indeed shows the opposite scenario: a Mastodon post with a preview of a Medium article.
