Update April 8: Twitter CEO Elon Musk said that Substack has been suppressed on the platform because Substack was allegedly caught trying to “scrape a massive portion of the Twitter database to bootstrap their Twitter clone.” The users of Substack, an email newsletter platform, are unable to embed tweets in their stories and Twitter users are currently unable to like or comment on a tweet that links to a Substack publication on the .substack domain. Users are sharing screenshots that say, “Some actions on this tweet have been disabled by Twitter,” when they try to post Substack links to Twitter. Reclaim The Net was able to confirm the restriction. Substack writers attempting to to embed tweets in their Substack articles are also finding that it doesn’t work. “Twitter has unexpectedly restricted access to embedding tweets in Substack posts” a notice states. Substack tweeted, “We’re investigating reports that Twitter embeds and authentication no longer work on Substack. We are actively trying to resolve this and will share updates as additional information becomes available.” Substack CEO Chris Bests tests the blocking of engagement with Substack links. Since purchasing Twitter, Elon Musk has made attempts to block other platforms from being linked to on Twitter – notably links to Twitter rival Mastodon. Musk also tried banning users from promoting their Mastodon accounts in their tweets or bios. The policy has since been reversed. However, this is the first time Twitter has blocked such a large up-and-coming platform.
