Security Considerations

While readthedocs.io is an established platform, these capabilities require extra vigilance.

Document Hosting

readthedocs.io hosts documents and pages shared via links. Because the domain is trusted, links pass through email spam filters easily. Attackers exploit this to host fake invoices, login pages, or malware download prompts.

User-Generated Content

readthedocs.io hosts content created by its users, not the platform operator. Individual posts, profiles, or pages may contain scams, misinformation, or phishing attempts that the platform hasn't yet detected or removed.

Custom Subdomains

readthedocs.io allows users to create custom addresses like "anything.readthedocs.io". An address like "paypal-secure.readthedocs.io" may look official but is actually controlled by whoever registered that subdomain—not Read the Docs, Inc..

Remember: The platform itself is established, but even established platforms can be abused.
