X Developers has released a major update aimed at combating AI-generated spam. Programmatic replies via POST/2/tweets will be restricted, allowing only replies that are mentioned or quoted by the original author. Non-replies will remain unchanged but will not be allowed programmatically. This restriction applies to Free, Basic, Pro, and Pay-Per-Use account types. Enterprise and Public Utility accounts are unaffected. Previously, Nikita Bier, X's product lead and Solana consultant, stated that they would utilize "all available tools and strategies" to combat bot accounts and undisclosed AI-generated content accounts.
