Temporary interaction limits give you control over who interacts with your public repositories. You can use them to force a cool-down period during heated discussions, or to prevent spam or abuse.

You can now set interaction limits for 24 hours, 3 days, 1 week, 1 month, or 6 months. This lets you control unwanted interactions on your projects.
