Organization owners can block a user to remove the user's ability to collaborate on the organization's repositories.
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
The user is not directly notified that you've blocked them.
Tip: If you're blocking a user because of a heated conversation, consider locking the conversation so only collaborators can comment.
To block an organization member, remove the user from the organization.
In the top right corner of GitHub, click your profile photo, then click Your profile.
On the left side of your profile page, under "Organizations", click the icon for your organization.
Under your organization name, click Settings.
In the Settings sidebar, click Block users.
Under "Block a user", type the username of the user you'd like to block, then click Block user.
