Organization owners can block a user to remove the user's ability to collaborate in the organization's repositories.

You can block a user from within your organization's settings or from a specific comment made by the user. When you block a user in a comment, you can choose to send the user a notification explaining that they were blocked and why. Otherwise, the user is not directly notified that you've blocked them.

When you block a user, you can choose to block them indefinitely or for a specific amount of time. If you block someone for a specific amount of time, they are automatically unblocked after the chosen time expires. If you block someone indefinitely, you can unblock them manually at any time. For more information, see "Unblocking a user from your organization."

Tip: If you're blocking a user because of a heated conversation, consider locking the conversation so only collaborators can comment.

At the time that you block a user from your organization:

  • The user stops watching your organization's repositories
  • The user's stars and issue assignments are removed from your repositories
  • The user is removed as a collaborator on your organization's repositories

After you've blocked a user from your organization, they cannot:

  • Cross-reference your organization's repositories in comments
  • Fork, watch, or star your organization's repositories

In your organization's repositories, blocked users also cannot:

  • Open issues or send pull requests
  • Comment on issues, pull requests, or commits
  • Add or edit wiki pages
