NEW: Twitter (X) is still throttling links to competitors' sites. We measured a consistent 2.5 second delay for Facebook, Instagram, Bluesky and Substack links, compared to a random control group of domains. That may not seem like a lot but it is 60x longer than other domains. This delay occurs via Twitter's t.co link shortener. AND we built a tool so you can test out other t.co links. Great collab with @dphiffer and Joel Eastwood. 🐢https://themarkup.org/investigations/2023/09/15/twitter-is-still-throttling-competitors-links-check-for-yourself
