Question Sources are meant to provide additional context for a question. Additionally, Sources need to adhere to the following:
- Sources are meant to provide additional context only; questions should be worded in a way that they do not depend on an external link for a person to be able to answer the question
- Sources should not refer to malicious content (e.g., spam, malware)
- Sources should be valid links (e.g., not broken)
- Sources should be relevant to the question
Question Sources that fail to meet the above criteria may be removed by Quora Moderation. Additionally, users who repeatedly violate this policy may have their account blocked or banned.
