Limiting interactions in your organization
Organization owners can temporarily restrict certain users from commenting, opening issues, or creating pull requests in the organization's public repositories to enforce a period of limited activity.
After 24 hours, users can resume normal activity in your organization's public repositories. When you enable organization-wide activity limitations, you can't enable or disable interaction limits on individual repositories. For more information on per-repository activity limitation, see "Limiting interactions in your repository."
Tip: Organization owners can also block users for a specific amount of time. After the block expires, the user is automatically unblocked. For more information, see "Blocking a user from your organization."
