You have a fundamental misunderstanding of what Section 230 of the CDA entails[1]:
> Section 230 says that "No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider"
What Section 230 says is that all providers of interactive computer services are not liable for user content. That's it. It doesn't matter what the interactive computer service does, or publishes or doesn't publish. If you're a provider of an interactive computer service, you're shielded from liability for user uploaded content.
