it also states:
> You retain all responsibility for Your Code, including Suggestions you include in Your Code or reference to develop Your Code.

If you use Suggestions, GitHub strongly recommends that you have reasonable policies and practices in place designed to prevent the use of a Suggestion in a way that may violate the rights of others.
