Since last May repository admins have been able to activate temporary interaction limits to force a cooldown period during heated discussions. Admins can limit comments, reviews, or the creation of pull requests and open issues to existing users, collaborators, or prior contributors.
For larger communities, discussions may span multiple repositories. Organization admins can now activate temporary interaction limits across all of an organization’s public repositories with a single toggle found in the new “Moderation” section of the organization’s settings page. Additionally, while active, repository and organization admins will see a banner across affected repositories indicating that the restriction is in effect.
For more information, see the organization-level temporary interaction limits documentation.
