X Deploys API Changes to Combat Spam Replies
X (formerly Twitter) has rolled out API-level changes designed to make it more difficult for bots to spam replies under popular posts. The move, intended to protect high-visibility content and brand engagement from automated disruption, restricts certain automated reply patterns. This change may alter how social listening tools measure sentiment and virality on the platform.
- The recent API change, effective February 23, 2026, specifically targets the `POST /2/tweets` endpoint. This means automated replies from an app are now only permitted if the original poster has mentioned or quoted the account associated with the app. - This restriction applies to the Free, Basic, Pro, and Pay-Per-Use API tiers, exempting only Enterprise and designated Public Utility applications. - The head of product at X, Nikita Bier, described the initiative as "Operation Kill the bots," aiming to shut down the primary entry point for low-cost, high-volume automated spam replies. - This move follows a January 2026 API policy update that banned "InfoFi" applications, which financially rewarded users with tokens or cash for posting or engaging with content, leading to a surge in AI-generated spam. - X has been actively purging bots, with one recent effort removing 1.7 million accounts that were overwhelming reply sections with spam and promotional content. - The platform's fight against automation has also included deploying advanced detection for accounts that don't show signs of direct human interaction, such as physical taps on a screen. - These API changes are part of a broader, long-term effort by the company to combat platform manipulation, which has included previous purges of fake accounts and testing paid verification as a method to deter bots. - The increasing cost and restrictions on API access since 2023 have already impacted how third-party social media analytics and management tools operate, forcing many to adapt their strategies or find new data sources.
