Twitter will no longer allow users to promote their presence on certain social platforms, including Facebook, Instagram, Mastodon, Truth Social, Tribel, Nostr, and Post. Twitter says it will take action against users that violate this policy “at both the Tweet level and the account level.” This means users can no longer include links to their profiles on other social networks in their Twitter bio, nor can they send out tweets directing users to check out their Instagram or Facebook accounts.
