@MarkJR84 @pixelfed @Mastodon @Gargron I added Indirectotron 9000 to my site to be a workaround in the meantime until the site gets blocked: https://blazeorange.ninja/id9k/. (Original at https://id9k.com/)
Unlike tinyurl or other link shorteners, this throws up a page with a link to what you were trying to link to, so Twitter can't just follow a 301 redirect. Hopefully this'll work until they start scraping linked pages for banned links.
