Overview
You may notice limitations on which X (formerly Twitter) accounts you can select to leave comments or replies on a post. This article explains the recent changes from X that affect this functionality.
New Restrictions on Replies as of 2/25/2026
To improve the quality of conversations and reduce spam, X has updated their API policies regarding how third-party applications handle replies.
We can no longer leave comments from an account unless one of the following conditions is met:
Post Author: The account leaving the comment is the same account creating the post.
Explicitly Tagged: The account has been explicitly mentioned (tagged) in the original post by the author.
Quote Tweet: The post is a quote tweet of a post belonging to the account.
If none of these conditions are met, the option to comment from that account may be unavailable or the attempt will be rejected by X with this error
Creating posts with @mentions is not allowed for your access package. In replies to conversations you are part of, you may only @mention users who are already participants in the thread.
Why X made this change
X introduced these restrictions to prevent unsolicited programmatic replies and automated spam. By ensuring that replies are only permitted when there is an explicit interaction (like a mention or quote), X aims to keep conversations relevant and high-quality.
